How did you test the memory? memtest is NOT sufficient.
Unless you removed half the memory and reproducted the problem, then
tried the other half and reproduced the problem, etc in various
combinations. If it does solve the problem you have found a bad stick
of memory. If it doesn't then you simply don't know if the type of
memory is simply bad for the system, or if something else is the
problem.

Not sure. Some people have been complaining about failure to boot
2.6.17-2.6.18 on some nvidia chipsets due to timer interupt bugs. last
I checked the kernel people were still waiting for an answer from nvidia
on how to work around the bug/setup the hardware correctly.
You could try booting with 'noapic' or some of the other options. You
could try booting with the option to set the system to only use one cpu
in case it is an SMP bug. Lots of things you could try. Perhaps
enabling remote logging over a serial port would be handy in case there
is a kernel crash dump that could help show the real problem (which of
course you can't see if running X at the time).
