After playing with kernel command line, I've found the problem does not occur
in a 64-bit kernel if mem=2G is added the kernel command line (the machine in
question has 3G of RAM). The higher the mem above that, the great the chance of
corruption - its hard to tell exactly when its an issue because its
intermittent - sometimes it work, sometimes it doesn't, (So far, 5 attempts at
2G no failures on either X for the framebuffer, whereas one start at 2G + 80M
worked but the second time it did not)
