Slowness of console is mainly from disabling cache on the
video RAM area.  I used to try to enable writh-through cache
and it had great effect.

Porting XFree86 to macppc is in progress.

Hmm, you may want to use AIX or OS/400? :-)

In my own opinion, NetBSD doesn't aim to optimize too much
for any arches, which easily break on other arches or MI/MD
separation.  Although it impacts speed some time, clean
design ensures stability and interchangeability.

e.g. XFree86 assumes x86 or PC arches in various place and
is hard to port to other arches.

It's no problem for me.
