True.

Yes, and because it also accurately tells you which memory location is bad. (This can't be easily done from user space, I gather). You can use this information to workaround the memory problem with the BadRam patch from Rick Van Rein.

True.

Actually lilo is just about enough for a such menu system...
Something like
image = /boot/memtest86 label = memtest86 image = /boot/vmlinux label = cpuburn root = /dev/hda2 append = "init=/usr/local/bin/burnP6" read-only image = /boot/vmlinux label = cpuburn root = /dev/hda2 append = "init=/usr/local/bin/testDMA" read-only
It would take some scripting to alternate the tests automatically, but perhaps it could be done.

AFAIK it's a pretty complete test suite VA uses (used?) for testing their hw. I'm not sure, though.
