** Description changed:

+ The current version of fglrx in Precise has a bug that results in an X
+ crash when playing Xv video.
+ 
+ This is a known issue and is expected to be fixed prior to the Precise
+ release.
+ 
+ We knew of this bug before updating to this driver, but made the
+ decision to proceed because the previous version did not work at all
+ with 1.11 due to ABI incompatibilities.  Historically, fglrx pretty much
+ always breaks during development, because we update the xserver and then
+ it takes some months to get a new driver from ATI.  This time we're
+ lucky in that the  driver mostly works.
+ 
+ [Workarounds]
+ * Switch to -ati
+ * Use oneiric until this is fixed.
+ 
+ [Original Report]
  After the upgrade, X seems to crash every time I try to play a video.
