   You can upgrade the SS2 and the IPX to a Weitek PowerUp chip which runs
   at 80Mhz. There does seem to be some talk in the mailling list archives
   back in 1996 about problems with NetBSD after this upgrade. I'm not sure
   if this was ever "fixed".

problems?  i have run several powerup's in SS2's and an IPX over the
years without incident...
