New Revision: 657

Added:
   branches/4.3.0/sid/debian/patches/453_ia64_fix_radeon_dri_deadlock.diff
Modified:
   branches/4.3.0/sid/debian/changelog
Log:
  * debian/patches/453_ia64_fix_radeon_dri_deadlock.diff: new patch to resolve
    constant ia64 DRI deadlocks. there are some indications that this is
    Radeon-specific, and some that it's not, so I'm just going to leave it
    as Radeon as not to give people false hope 'till I can confirm it. Are
    there even any other cards DRI supports that are made for ia64 anyway?
