Just out of interest, have you tried it using lower settings for the mem=
option? You could have options in the BIOS turned on that actually take
some of your available memory away from your main memory pool. Some
on-board video cards use the main memory pool for their ram, and settings
such as "System BIOS Shadow", "Video BIOS Shadow" and the "XX000-XXFFF
Shadow" options in your BIOS setup all detract memory from the main memory
pool of the machine.
At boot, check the final value of the ram count and insert that value into
your mem= option. usually this option is in Kilobytes, but don't worry,
just add a K instead of M on the end and the kernel will understand.
I'd hazard a guess that this is what is wrong, but YMMV.
