Ouch, PCI really should use new driver model. I have not known about that. I'll look into it. > The "initiators" all talk to _both_ infrastructures, but they > don't talk to the driver model stuff in the same way.

IIRC, I had SAVE_STATE there at some point, and there was some problem.

Otherwise it should be ready, except for APM. Pavel -- When do you have a heart between your knees?
