peter 22637b0692 Commit Bosko's patch to clean up the PSE/PG_G initialization to and 
avoid problems with some Pentium 4 cpus and some older PPro/Pentium2
cpus.  There are several problems, some documented in Intel errata.
This patch:
1) moves the kernel to the second page in the PSE case.  There is an
errata that says that you Must Not point a 4MB page at physical
address zero on older cpus.  We avoided bugs here due to sheer luck.
2) sets up PSE page tables right from the start in locore, rather than
trying to switch from 4K to 4M (or 2M) pages part way through the boot
sequence at the same time that we're messing with PG_G.

For some reason, the pmap work over the last 18 months seems to tickle
the problems, and the PAE infrastructure changes disturb the cpu
bugs even more.

A couple of people have reported a problem with APM bios calls during
boot.  I'll work with people to get this resolved.
