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.
