I can confirm severe (pmap, uvm related?) problems with recent
-current on my tibook, especially with nfs. They are of two kinds,
depending on using NEWPMAP or not:

With NEWPMAP the kernel doesn't panic, but disrupts many (not all) nfs
files (fatal if using /usr/*src nfs mounted). Most obvious thing I see
is the effect on 'vers.c' created on the fly in
/sys/arch/macppc/MACHINE/compile: Except the first 'ostype' line most
of the time (not always!) the other lines are simply missing! I've
never seen a disruption within a line.

There is also disruption on object files which I haven't examined.

Without NEWPMAP I don't see these file disruptions, but get kernel
panics very often.

Beside that I tried the NEW_TOOLCHAIN to compile kernels: Only with
'-O' I get working kernels. With standard '-O2' it panics somewhere in
the device attachments.
