Sure. Just wanted to make sure you had the full set of piglits
available to you :) BTW, if you've only done fs but not vs/gs, you can
add things like -x vs -x gs to exclude a lot of the piglits that you
_know_ will fail.
There are some good tests in there... things like dmat4*dmat4 will
give your RA a nice stress...
