If you have a null modem cable and another machine with a serial port
available, you could try booting with the kernel outputting to the
serial console to try to catch any kernel messages related to the
lock-up.

For example, append " console=ttyS0,57600" to the kernel command line
via grub/lilo, and have minicom configured (Ctrl+A, P) to match ("57600
8N1") and to capture to a file (Ctrl+A, L) on the machine at the other
end of the cable.

Also you might try, if possible, to pull a memory module or two and see
if the problem disappears.

Oh, and you're not using a proprietary ATI driver by any chance, are
you?
