Thanks for the reply, Klaus. I think I've gone over the trouble-shooting mentioned in most of those articles. I can't do any AHT stuff, because the computer won't boot from anything!
I should have mentioned that I did try booting the comptuer removeing and switching the RAM... nuthin'!

you said 'stock' that means old FBDIMMs and equally old GPU, and probably not really enough RAM.
AHT is not really a system you boot, as a program. And is only on the OEM DVD it came with.
You can pull all the hard drives and run it.
I would pick up 8GB RAM from Amazon for $60.

Thanks for the reply the hatter. I really didn't want to go spend a bunch of money on this computer in case it was like a dead logic board or something. After discovering the diagnostic LEDs this morning, I was able to confirm that the machine was booting without a GPU, so I made a fresh installation of OS X with ARD enabled to verify... and it boots right up.
So I've tried a couple of ATI Radeon X1900s I had around, but none would work, so I guess maybe they're not compatible? I'll see if I can get my hands on a replacement for the nvidia card that came with the machine.

The smartest replacement for any of these old graphics cards is the Apple-firmware 5770, about US$250. It works in every model Mac Pro and drivers are in 10.6.5 and later.
Buying a refurbished old card is not recommended.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

Thanks for the advice, Grant. I'll order the card ASAP.
