Well, it did. The sympthoms are the same as before: incomplete
undocking. The 16:00.1 device (HD audio controller on the radeon card)
has disappeared from lspci output, while 16:00.0 (the radeon card
itself) didn't, and the "Docked" LED didn't turn off. Fixed up by this
command:

fuser -k /dev/snd/* ; rmmod snd-hda-intel

thus confirming again that the extra references that acpiphp waits to
go away are from open fds.
