You can probably leave Power Math on, all it does is install some traps
that use Daystar's faster floating-point routines (or something like
that). I seriously doubt that NetBSD is barfing on that. It will most
like barf on the Power Cache, though.

I believe that this does now affect everyone (I used to be able to leave
in on prior to 1.2, but something must have changed ;-)
BTW, this is more or less in the FAQ. The section on what to do if
NetBSD doesn't boot explicitly says that you should turn _all_ extensions
off (with the _1_ exception of MODE32 if you need it). This implies
turning off Power Central as well ;-).
Later.
