Probably a stupid thing to do anyway, but I was trying to troubleshoot a problem I'm having with my GUS PnP. It worked with 2.0, but doesn't with 2.2. Having some sort of weird IRQ problem. Anyway:

I haven't looked at the code to see what is the problem yet, but I figured I'd post it here for posterity at least. I'll see if I can squeeze in some time tomorrow.
