The problem is that vaQueryConfigProfiles() will always report H.264 even
if the underlying HW does not support it, or the necessary kernel module
is not installed. The patch I have just sent normally fixes the issue.
Likewise for VC-1 detection. I have not formally tested it on older GM45
chipset as my platform died.
