This was fixed a few days after 2.6.10 was out. Some drivers that filter
hotplug events increase the sequence number but don't send any event.
Martin: Please try 2.6.11 if that helps as for the HAL part there is no
easy fix I can think of. And udevd has the same problem with that
kernel-version.
If ubuntu can't catch up with the 2.6.11 kernel, but that kernel solves
the problem, I think the best solution would be to backport the fix to
your kernel, instead of work around it in udevd and HAL.

There are still problems with some drivers, but that may work better if
there is no real fix for the problem, yes.

Thanks,
