I have the same problem(choppy sound + wifi restarts) on my Thinkpad T60 w/ ATI x1400. There were many "hpet increased min_delta_ns" messages in dmesg's output and decided to try to disable HPET. Adding "hpet=disable" to kernel options seems to mitigate the problem to some extent - i.e. it seems to appear less frequently. After switching to 2D desktop the problem seem to disappear. If the bug is due to some sort of race condition however, it's possible I just got lucky so far ...
