First, rmmod works again (thanks ;-)).

My box is still hanged solid on resume (swsusp) by the drivers:
ohci_hcd
ehci_hcd
yenta_socket
possibly others, too. To avoid this, I had to revert the following patch from
the Len's tree:

# Delete PCI Interrupt Link Device .resume method --

# not the Link's job to remember what the devices want.
#
# This addresses the issue of attempting to run
# the ACPI interpreter too early in resume, when
