It works, thanks.

Now, I'm able to suspend the box, seemingly, but there are some problems with
resuming. There is a crash related to USB (gets "fixed" if I unload usb_ohci
etc. before suspending) and a preepmtion problem. I'll send some traces as
soon as I can get output from the serial console. In the meantime, I'll try
to compile out preemption.
