Hi Harley,

   Could you please try the patch below and let me know if this works
correctly for you? My preference is for a single binary that works
with all drivers where possible.

   Do you know if there's any equivalent extension for ATI cards? If
so it'd probably be worth adding, but unfortunately I don't have any
ATI hardware handy to test with.

Cheers,
Nathan
