Oh, it can be worse than that. It has been claimed that the wireless
card whose details I just posted in another thread has a kernel driver
that should handle it. It doesn't. As can be seen in the posting, I
use ndiswrapper to wrap a manufacturer's proprietary windows driver
specific to that *chip*, and have to blacklist the kernel module so
it doesn't get linked in first.

I don't know whether you will have to get a manufacturer's driver,
nor whether you'll have to blacklist whatever driver is running the
video now; what was it, Gallium 0.4 on llvmpipe?
Other people on the web might.

Well, if you find one, so much the better. But it would be unusual to
find a graphics chip that has only ever been used with one CPU chip.
