Kernel 2.2.x did not support more than 2GB of memory because the hardware
scatter/gather code used to support more than 2GB was never ported to it.
For that, you have to go to the 2.4 kernels.

Yes.

This (failure to build a working SMP kernel) is a long-known problem
with GCC 2.95.x; you must migrate to a later (3.x) version of GCC.
Good luck.
