hmmm, i built ati 7.5.0 driver against -current and it does not
seem to be a progression.  it seems to work for basic stuff, and
upto and including XVideo, but anything GL now errors out, and
eg, this on the console:

   DRM error in radeon_cs_ib_chunk: Invalid command stream !
   radeon0: warning: r600_cs_track_validate_cb:419 cb height (300, 0x10, 4) invalid
   radeon0: warning: r600_packet3_check:1737 invalid cmd stream 498

the above is from 'glxgears', but real apps also fail the same.
