The way to fix it is to add the line "mach_options= -m90" (for 90MB) to your lilo.conf. This will limit the amount of memory MkLinux recognizes.

Reportedly there is a physical limit as well, where if you have more than that amount not even the -m option will save you. In that case, donate a 128MB DIMM to the needy and receive a hefty tax break.
