I suppose we could simply blacklist any G200eV with a subsystem vendor

0x1014 (IBM) until we figure out how to correct the driver.  Our

be deprived, but as it seems to be broken across most of our product
lines I
doubt any of them are making serious use of it anyway. :)

Something like this? 

Does X work with the open source drivers ? In that case a better
approach would be to try to figure out what's different between the way
the 2 drivers setup the card registers and fix matroxfb..
