[9fans] Matrox G400 driver status

[George Michaelson]

I posted two on this, but neither showed up in my local newsthread
leading me to suspect a mail:news g/w died. Thatm, or my incoherance
did me no favours again.

booting with an otherwise normal plan9.9fd I got the predictable:

I added the device probe string for my Matrox G400 into vgadb but
all it does it make the boot floppy print a different failure:

I'm guessing the black art of making mostly similar cards work is
not as simple as I'd hoped. 

Has anyone progressed further here? is there a new hwgc entry or
something binaryish which is defeating me?

cheers

PS first one to hit me with a 'buy an obsolete card and stick it in'
gets a free hollerith card pre-printed for basic-by-numbers coding.

I have a ream of them, they make good roaches if you don't mind the ink...
