Very crude hacks that appear to sort of work

  I have done some printk-debugging, and come up with some preliminary results
and a patch that works in my minimal testbed kernel, suspending the fb-console
in single-user and resuming multiple times. It appears that
acquire_console_sem() may be hanging things, and it is pretty clear that one or
more of the pci calls, such as pci_set_power_state(pdev, PCI_D3hot), are
hanging. I'll see if this works multi-user suspending from X.

  This is *not* recommended as a patch, just as an indication of where the
problems may lie.
