To add a bit of newer information but no solutions yet, my development box died of heat overload a week ago. I ordered a new computer because it was pretty old anyway but the new computer just came in yesterday. I thought just for grins I'd put ubuntu on it to check out orca and X so will take at least a few more days before I can get back to the hunt for what changed. The fact is that the way some interrupts are handled got changed in 2.6.20 which I haven't figured out yet. It only affects the dectlk driver because for some reason it is the only one using this particular interrupt routine. This is all part of Mike MacDonalds changes to handle read to end but I haven't figured out why he did the dectlk this way instead of the way he did the others. The point is though that I haven't actually figured out what changed in the kernel to cause this new behaviour.
