This was on a laptop, p4 1.7Ghz, 512M ram, radeon video chipset, dri
enabled. The kernel I was running was patched with the "illegal" drm low
latency patch (which does a reschedule with a lock held but gets rid of
10/15msec scheduling delays - I know, bad boy, no cookie :-).

I don't know, I will retest when I have a chance. This is further
complicated with the problems jack has with 2.6.x/nptl. 

If I find a moment I would like to catch up to the latest patches and
get a newer 2.6.x running before retesting. I've been on a trip and then
busy with a big move and have been trying to keep with the latest (and
salivating over the latencies reported on 2.6.x)...
