I have mythtrunk up and running with the 180.11 drivers and it seems to run anything I throw at it!!
1080i runs at about 9% CPU and 720P at 5%.  I'm loving this!!!
There are some problems with mythfrontend segfaulting the first time and at somepoint I got white blocks for menu items.  Restarting mythfrontend seems to have fixed it.  I'm happy.
