Hmm, I've been running GATOS binary modules built for Linux to provide
XV support for an ATI Mobility Pro LY for some time (at least 6-8 months
and some 4-5 different "experimental" versions so far, all have worked
great):

Seems to work pretty well from a stability POV, no issues that I could
point at the module for. And certainly the hardware scaling and color
transforms work way better than they do without the module ;-)
