I vaguely remember that if you have some memory hole setting in the bios
turned on, this can happen.
This happened to me on an old compaq server but I couldn't find any
memory hole settings, still, its worth checking anyway.
Otherwise the bootprompt howto has the answer,
adding something like append = "mem=256m" to /etc/lilo.conf should do it.
If you tell the kernel you have more memory than you really do it will crash,
I've heard its safer to use the the number the bios reports when it boots,
normally in kilobytes.
