1.0b in the card should be fine since that really only handles the radio
link; I used bt3c(4) for a long time with DUN and keyboard/mouse.

There might be problems when the remote bluetooth RFCOMM protocol is 1.0b
and overruns can happen, since our RFCOMM code only does the newer
(mandatory from 1.1) credit flow control. I see no real point to
implement* the old style since overruns could still happen because of
packet lag.
