[r300g][r600g] Black gap artifacts when playing WoW
Submitted by Chris Rankin

When playing WoW with the latest Mesa from git, sometimes black lines and gaps on the screen. These black spaces appear momentarily as I move around, like intense shadows. Sometimes, the entire screen appears to go blank.
export RADEON_DEBUG=nohiz makes no difference, and no "acquiring HyperZ" messages are printed on the console.
This is with a T60p laptop with a M66GL (RV535?) chip, running a 32 bit Linux 3.6.9 kernel.
