Cool, I'll give that a try.  I downloaded the gzipped file from that link
and extracted it into my /usr/lib/xorg/modules/drivers.  Now what do I do
with it?  There is no configure and no makefile.  Do I just overwrite the
existing qxl driver sources with it and remake?

What does that mean?  How would I do this?  Do I need to download
something else?
