Tohru Nisimura has fixed my busted changes to the sfb driver.  AFAIK
we still havent' tried it on a PMAGB-BB (sfb board using the alternate
crystal for a VR297 or other 1024x876 DEC monitor), which was the point
of the changes.

I've built a GENERIC -current kernel and put it on
ftp.netbsd.org://ftp/pub/NetBSD/arch/pmax/sfb-test-kernel/netbsd.aout
Could someone with a PMAGB-BB let us know if it works for them?

thanks
