Your best chance would be to reserve this memory at boot
time, maybe you'll even need to change MAX_ORDER in
mm/page_alloc.c to do this...

Btw, I hope you are aware that kernel 2.4.2 is old and
has a number of (security) bugs. Unless you have very good
reasons to use this kernel and you are certain that the
machine will never get a network interface you'll probably
want to upgrade to something newer.
