Any reason 128MB is not picked up?

Does the kernel support more than 64MB? We have a couple
machines with 128MB and I'd not clicked on until just
now when checking out a new server that although the bios
shows the proper number on boot, if you later look in
/proc/meminfo you only see 64M.

2.0.28 and 2.0.29 and 2.0.30.

I'm not all that familiar with Intel, I'm mostly a 68K NeXT
type.

Ideas?
