Dunno....I'll have to try 4.1.0 again on mine since I never had a problem
with DRI on my V3-2000.

IIRC, newer kernels have the revised DRI stuff in them for 4.2 (don't hold
me to that...I haven't checked to be sure yet).

I got that far awhile ago when trying to fix FlightGear, but ran out of
time to fix further.  I believe that FG has some 64-bit issues, but it
would take some time for me to find them.  I can start doing so, if you'd
like, but it will probably take me over a month to really make any
progress due to RL time constraints.
