Sorry, I was wrong. No difference between 2.6.39.2 and 3.0.4.

OTOH, I tried 2.6.32.36, and kms worked, although "EnablePageFlip" "off" was
necessary; without it, the screen is black, showing nothing. vblank_mode=0
doesn't affect fps of glxgears.

Below I've attached dmesg of 2.6.32.36 (good) and 3.0.4 (bad).

You'll have noticed both have a line
  radeon 0000:01:05.0: PCI INT B -> GSI 19 (level, low) -> IRQ 19
but in the good, there's also a line
  radeon 0000:01:05.0: irq 26 for MSI/MSI-X
and /proc/interrupts says only irq # 26 is used in the good. (In bad, it's 19.)
