Whoa, nice.

There's a known gotcha though. If you have a newport and use serial
console (ie. even PROM doesn't touch the board) you get a hang during
boot. I haven't been able to test this (due to lack of correct serial
adapter, curse SGI for using such a crappy connector) but my guess would
be it hangs in the resolution detection. Working on this.

I'd very much like to be able to program the timings myself to avoid the
dependency on PROM setting things up but currently lack the means to do
so, working on it though.

I think either a) the board revision check is busted or b) the cursor
bug check should not use board revision but rather the VC2 revision.

Also I've one report that x_offset needs to be 29 instead of 21 (works
for my board) or 31 (what the docs say). I'll whip up some test
"paetches" later on.
