Yes, I'm fixing that.  configs/debian-dri_powerpc was a faux pas on my
part.  I wondered why the file existed at all but nevertheless went
ahead and added all the stuff it requires to actually work as
documented in debian/README.build.

Now that we agree on the purpose of that file...

configs/linux-dri-ppc says:

OPT_FLAGS = -Os -mcpu=603

What does that map to? G4? G5?  Does gcc 4 support altivec in any way?
 Would it be worth enabling that?  Do other non-Mac PowerPCs have any
use for optimized DRI drivers?

Hmm... I'll look at that.  Thanks!
