I fixed request_region() and friends months ago, even finding and fixing
a race condition. I mailed the patch to Linus, but I guess it got lost
in his mailbox.

Anyway soon after Andrew E Mileski started to get into PnP support so
I passed my changes on to him and he's generalised the whole area and
worked them into a fix. I'm surprised to find his changes didn't get
into the 1.3.x tree. PLEASE put them in, and preferably into 2.0.x !
