When I launch pulseaudio, a bunch of the following line is dropped to dmesg:

Well, it basically means that your hardware is flaky. The driver tries some workaround for the buggy hardwares, but it didn't help in your case.

alsa-info output is at: http://www.alsa-project.org/db/?f=fd7037731d908e4287e1d457de6a1483062b2130

I'm using 2.6.30_rc3 with:

• 20090421 snapshot of alsa-driver,
• 20090410 snapshot of alsa-lib.

Pulseaudio version is 0.9.15, timer-based scheduling is enabled.

Try to disable timer-based scheduling. The timer-based scheduling requires the frequent inquiries of the DMA position, and your hardware is buggy about it.
