OK, here we go. Enclosed is my current patch that changes some of the PowerMac specific stuff in a more logical way and get rid of ohci->sleeping (I didn't get rid of ohci->disabled yet).
So far, suspend & resume with no device plugged works, BUT, once resumed, I get an irq storm of about 200000 irqs/sec on each of my 2 OHCIs, which slows down the machine dramatically until I rmmod & insmod the driver. I haven't yet investigated what interrupt the HCI is trying to send yet nor did I try with USB devices plugged.
Any chance of splitting out the "remove ohci->sleeping" bits by themselves? If you don't, I'll want to do that.
There seemed to be some oddnesses in there, like returning IRQ_NONE before looking at the IRQ.
