I just remembered, hibernated doesn't work for me either when
snd_bt_sco is *loaded*. However, if there are no processes are using
it,  you should be able to remove it using the rmmod command,
   i.e. rmmod -w snd_bt_sco.

For this reason I have added:

  killall kmix
  killall btsco
  (sleep 1
  killall -9 kmix
  killall -9 btsco)
  rmmod -w snd_bt_sco &

To the start of my /usr/sbin/hibernate file. This allows me to
reliably hibernate (with kubuntu 5.10, you may have to kill a
different set of processes, though I doubt that you will have to kill
all processes listed by <lsof | grep snd>) . I have also added

  modprobe snd_bt_sco

to the end of this file so as to reload the module when coming out of hiber=
nate.
