i'll try tomorrow...

meanwhile, i watched a film and did some other things and now glxgears
doesn't start anymore:

dmk at schatten ~ $glxgears 
Mesa: Mesa 7.8-devel DEBUG build Mar  2 2010 19:57:41
Mesa warning: couldn't open, software DXTn compression/decompression unavailable
Mesa: Initializing x86-64 optimizations
Running synchronized to the vertical refresh.  The framerate should be
approximately 1/8504368 the monitor refresh rate.
X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)
  Major opcode of failed request:  133 (DRI2)
  Minor opcode of failed request:  8 (DRI2SwapBuffers           )
  Resource id in failed request:  0x1c00002
  Serial number of failed request:  32
  Current serial number in output stream:  32

does this 1/[bignumber] look alright? maybe that is the culprit...
waiting some 10^6 time ... i think the monitor refresh rate is
something about 60 hz? not over some khz?  which means that 1khz/8504368
is something about 1/8500 hz  which amounts to about 140 secs? (it is
late and i may have switched nominater and denominator a bit too
often... but if i don't have crossed anything, than that could
cause some hang... don't it?) 


p.s.: my software stack is git master of libdrm, mesa
and xf86-video-intel as well as xserver-master + krh's pull request, so
that it looks light that:
