Could someone test this patch out on an SFB?

Any kind would do, but one of the PMAGB-BB cards jumpered for an
alternate crystal -- 1024x876 or 1024x768, compatible with fixed-freq
monitors for CFB or Persnal Decstation, respectively -- would be most
useful.  It might even get rcons working on those machines, unless I
made yet another dyslexic horizontal/vertical boo-booo...
