Correction for typo:
To reset to the original state later after safe mode or if there are problems with fsck:
sudo mv -n /sbin/fsck_hfs /sbin/fsck_hfs_workaround
sudo mv -n /sbin/fsck_hfs_orig /sbin/fsck_hfs

I had suspected a 64bit clean issue when folks started reporting issues with memory configurations. I also saw a bug report filed against fsck_hfs on it's lack of pointer cleanliness..
Great to have a workaround!

It worked for me too.
Unfortunately my computer was experiencing some "spinning ball" lately and when checking the syslog after the safe boot procedure I discovered some "disk0s2 I/O errors", and a coupple of hours later the HD crashed... :-(
So it's in the Apple store now to get that fixed.
Took the oppurtunity to let them check my screen/display too, cause it has some flaws.
Hope they will replace that too.
But thanks for your clear protocol on how to work around the 2GB.
Still think this is a bug, but I will get into it again after my 27 inch iMac returns from the shop.

Thank you for your solution.
I wonder if it could be possible editing the MacOS startup procedure rather than changing the executable. Anyway, this is simple and clean.

I received my iMac back, with a new harddisk and a new display.
I put back my system using Time Machine.
Then I forgot to try the Safe Boot
Then I installed the 10.8.4
And then I tried the Safe Boot, worked good.
So my problem is fixed, probably by 10.8.4.

Great job, isenberg.
I had lots of messages "MDS Error: unable to create user DBs in /var/folders/..." in my system log.
Many post advised to boot into safe mode, but when I tried to do so, it always stuck at the same place.
I was close to a reinstall, when I found your post.
You saved my day!

I am getting the unfinished scan, but my machine does not hang. After about 1/3 of the progress bar, the screen goes black and then the iMac re-boots normally.
I have never seen Safe Boot Mode.

I am having the same problem ... safe mode boot progresses about about 1/3 then screen goes dark and late 2012 iMac reboots. Have you found a solution to this problem? I am running Mavericks 10.9.1.
