One other thing to consider
One other thing to consider is that it's entirely possible that the MLB simply cannot handle 1GB density RAM. The G5s are pretty old, and 1GB RAM modules quite possibly didn't exist when the unit was being designed, or were so expensive at the time that the system designers did not bother factoring them in. It's something often overlooked by people, that to a computer there's a big difference between 2x512MB and 1x1GB. A lot of people may just see that the maximum supported RAM is 1GB, and so think that they can get to 1GB any which way they please, but it just doesn't work that way in the real world.
2x512MB might be the maximum supported configuration for that unit. If the 1x512MB config works regardless of memory bank, then odds are the MLB is fine, and the problem is you are trying to use a RAM density that the unit can't handle. If you have another 512MB module, you could try putting the both of them in to see if it will POST and boot, and I'm betting it will.
