dmesg without MSI

If I boot the current d-r-t kernel with MSI enabled the radeon module doesn't fire any interrupts. Without the interrupts and vblank_mode in driconf set to 3 the screen stops refreshing.

This is always reproducible. To make it work again I have to boot with pci=nomsi.

Software versions
kernel current d-r-t (2.6.35-rc2)
ddx, mesa, xserver git master

Hardware
Radeon X1950pro RV570 (AGP)
