I assume this is a regression. 2.6.35 didn't do this?

Yes, I suspect 6e86e0419471d11ed3d4d46039ee90e8cb85806c is the culprit.
I'll send a patch to Dave, but I can't test it personally, I don't have
any hardware the manufacturer has configured in the way it'd need to be
to trigger this.
Ben.

I'm really not sure when it was introduced, since I've switched to
