Cameron do you think this is okay for me to commit to -current and then to
-stable after a week. I've been running this on -stable. It compiles in
-current and I don't see why it wouldn't work there. However, my laptop
doesn't like to suspend and resume very well in -current so it's hard to test
there. Also it's a bit of a hack and I was wondering if you as the sound
guy had any objections. It better then the now when sound is dead after
a resume and needs either a kldunload/kldload cycle or worse a power cycle.
Thanks,
Doug A.

| Thank you very much...
