I'v done a complete reinstall so its not a driver or Kext conflict.
Not a valid conclusion . Different video drivers are used in safemode than normal boot. If you have ATI hardware, One of my posts near the end shows how to delete the drivers that are causing you the problem.
Look through this thread. see the second page.
You need to find out who manufactured the video hardware.
see page two. my post are by rccharles.
For ATI hardware on a G5 iMac see:
I didn't have any luck pointing to a post. See page two.

Thanks Robert! I love these Communities. Only 3 weeks ago I came across so many other possible solutions and wound up deleting my entire HD (backed up 3X) Though and purchased a new mini with Lion cause I was in a jam after 3 weeks of almost just getting the right fix.(almost ready to do some soldering from one post) Wish I posted instead of being just a looky loo for the answer. You nailed it. Stil it was an educational journey...and I love my dear PPC G5 on Leopard so much more for it. The new systems just like a synoym for American business, Too much marketing fluff and pretty disposable. The old stuff is built tried and true to last. I love the speed of the graphics in my new system but thats about it, they can have the rest. I saw a post that someone said Lion is Apples "Vista" I tend to think Jobs knew and left on a high note. My Mac is not an Iphone and I will not be locked into purchasing from one source. Even the Mini has no DVD/CD Drive.and Lion drops legacy support. This will not go down well in the history of the company. Long live my G5. I will not purchase another version of the same programs I owned and bought 3x already.

I tend to remember going through this about 7 years ago too.

Thanks for the kind post.
You can see a lot of trail & error was required to find the solution. And, I ended up guessing you could delete a video driver.
I read that there are a lot configuration options to Lion to get it back to being a Mac. I'll miss PPC emulation the most if & when I go to Lion. The only downside of the Apple GUI design is when they move to a new GUI design, they don't include enough configuration options.
Read where Microsoft is trying to preserve their existing Windows interface while adding a tablet approach. Should be a laugh. They call it something of a middle of the road aproach.
to Microsoft .. ..

Sad to Report against my better Judgement I shut off the iMac on going away for the weekend. The screen will no longer come alive. Not even a glimmer- I guess the last suge of power was the final breath of a dying video board. I now have to stare at a mangnta filled screen on a bug ridden New Mini running Snow Leopard to complete work in non-lion software. With no mention of any fix ahead for the Mini and HDMI connected to a new Vizio - I may be forced to buy a used PPC off craigs list to muddle through. Shame on Apple that I favor the older equipement and software over the new stuff I just bought.

I did a search on replacement logic boards. I got a reminder of the g5 capacitor problem. Capacitors fail a lot on the g5. There are sites with pictures. Could be time for you to learn hardware repair. Also, there are local Apple Pi groups to help you out.
actual logic boards google iMac G5 PPC logic board
Seems better to buy a used machine. Just the tower not an all-in-one.
I heard the servers were noisy:
I guess they didn't have a g5 mini???

Thanks I did trip across some of those previously before finding your simpler solution. BTW your my go to guy on video issues now. Please check out my new video issues post. I'd like to see if you have any suggesiton cause I think removing some type of duplicate driver may be the solution again. I posted in Mac-mini and Snow Leopard the same post but added more detail on the one which seems to be getting responses.
