Didn't have time to look into this yet, but just retesting all the apps
I had trouble with vbo_0_1_branch some months ago showed that the quake3
intro screen is now fixed (with r200). ut2k4 and doom3 segfault though
(ut2k4 at intro screen, doom3 when entering game), both also fail to
recover from the segfault as they normally do (and then exit nicely)
though I guess that's due to some locking trouble, at least that's what
I guess from gdb's output:
Program received signal SIGINT, Interrupt.
0xffffe410 in __kernel_vsyscall ()
(gdb) bt
#0 0xffffe410 in __kernel_vsyscall ()

#2 0xb7c4dd81 in _L_mutex_lock_4119 () from /lib/libc.so.6
#3 0x00000000 in ?? ()
Anyway, here's the bt of the segfault (in doom3):
Program received signal SIGSEGV, Segmentation fault.
