I've had good results with 2.6.21.1 (even running tickless :)) on these

Not yet. Coming up... I'd prefer not to rely on new kernels at this
point though - but I can certainly try it just to report on current status.
I just checked and the fix I was referring to earlier didn't make it into
2.6.21-final. You can get 2.6.21-git1 from kernel.org which has the fix. See
http://www.kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.21-git1.log
for the changelog and commit id's for the patch:
