Yes, that would be far better.  The Mesa code has really rotted - it
only does CPU detection for 32-bit CPUs, and doesn't support checking
for any of the modern features.  The Gallium code looks much nicer.

Patches to pull that out into a common area would be fantastic.  I meant
to do it several months ago, but never found time...
