Its been a while since I compiled a kernel, but I believe there used to
be a 'bigmem' option that needed to be enabled if you had more than 4Gig
of RAM in the box.
I dont recall which kernel version this was in - try pulling down a
2.4.x kernel and running the make xconfig (or whatever) on a box and
seeing what options there are and comparing it possibly to your custom
kernel's 'make xconfig' ?
