[``cnfg 1'' output of sfb snipped]

This looks a pseudo-standard 1k VGA output, 1024x768 at 72 hz, with
the porch timings as described in the PMAGB-BA output.

See the table in Joel McCormack's WRL techreport on the SFB.
If memory serves, Simon Burge emailed the table in November last year.

It would be truly wonderful if someone could get legitimate access to
the DEC Ultrix sfb code that handles this.  The TR also suggests that
using the Ultrix Xserver would be significantly faster than the MIT
server.  

It'd be great if DEC would release that code; its not like they're
ever going to recoup more money on mips TC systems or upgrade the
software.  Sigh. Knowing exactly _what_ to tweak on the sfb chip to
compare the clock counts would be nice. Anyone know if the ALpha TCA
does the same thing?
