cirrusfb status report

[David Eger]

So I have the cirrus fb driver ported to 2.6, with a few caveats:

+ ZORRO is busted (don't have the hardware... once i get things nice
  on x86, I'll look about fixing ZORRO.  Hey geert - do you still have
  hardware to test this>?)
+ the only mode it likes is 640x480 (but then, that's the only one 
  i got working with the 2.4 driver, so, maybe that's not a regression...)
+ inserting it as a module just leaves crap all over the screen

I ended up doing a lot of things like 's/fb_info/cinfo/g' so the diff
is gonna look like the whole file, though I haven't (yet) changed any
of the actual register-writing logic.

Is there anyone else with cirrus logic video boards lying around who will
be interested in testing the new driver in a couple of days?

I never had a Cirrus Logic board for Amiga. Still have the Amiga, and I can do
cross-compile testing ;-)

Perhaps some PPC/PReP guys?

I just bought this card so I'm willing to give it a try.

The cirrusfb driver is for some old cards.  Garage sale? ;-)
I finally tracked down a screen corruption issue.. you have to wait
till BLT's are done to do a pan().  This probably affects 2.4 as well.

The patch is at:

http://www.yak.net/random/fbdev-patches/cirrusfb-2.6-update.patch

ZORRO is still busted, and my monitor freaks out when I try anything
but 640x480x8.  Is this something that modedb could help out with?
If you can figure it, I'd gladly accept a patch for it :-D
