I think you're giving up too easily.
I've seen a similar message to yours on my G5 before. My G5 is fine, I
just had some RAM seated poorly. I reseated my RAM and everything was
fine.
It seems your problem is a RAM issue. It appears slot 4 is bad. Are
you sure you've got the correct RAM? It takes PC2700 DDR. You can use
PC3200 DDR also, but NOT PC2100 DDR.
As for the AHT, are you sure you have the right version? I believe the
correct version is 693-3994-A which should be printed on the disc. All
versions are available for download here:
<http://www.info.apple.com/support/aht.html>
Also, on the resetting the PMU/CUDA, Apple has this article:
<http://support.apple.com/kb/ht1939>
I've found the removing the PRAM battery and letting it sit overnight
(or 15-20 minutes) without the battery can sometimes help. I normally
press the CUDA immediately after removing the PRAM battery, and again
before reinserting the PRAM battery. If the PRAM battery is dead, this
can cause all sorts of strange problems, so being certain the PRAM
battery is good is really important.
I'd recommend reseating EVERYTHING (video card, ATA cables, etc.), and
then burning a new copy of AHT. Then use a single stick of RAM that is
KNOWN GOOD PC2700 DDR or PC3200 DDR, in the 1st RAM slot, and try
booting the AHT disc using the Option key at startup. I think there's
a good chance you can get this working perhaps?
