IIRC, this is a BIOS problem; it can only report a maximum of 64 MB of
memory.  To get your kernel to recognize all your memory you need to
put:

	append="mem=128M"

in your /etc/lilo.conf, rerun lilo, and reboot.  Note that your system
can get seriously fscked if you don't actually have 128M.  Read lilo(8)
and lilo.conf(5) before trying anything.  There's also some stuff in
/usr/doc/lilo/*.  The BootPrompt-HOWTO also has a few things to say on
this.
