whereas it still affected mesa 7.7 a couple weeks ago, today's snashot now
looks "fixed" (aka no more segfault but black window instead).
Note mesa 7.5.2 still exhibit the exact same segfault.

Summary (tested today on RV350 AP [Radeon 9600]):
- 7.3: OK
- 7.5: BROKEN
- 7.5.2: BROKEN
- 7.6: OK
- 7.7: OK (as of 20091005)

Here's the diff between not working 7.5.2 and working 7.6:
