Yes.  Only one driver can claim a physical device (multi-function
devices have to be treated a busses with several children).  There are
a number of drivers in FreeBSD that have overlapping capabilities - in
which case the safest approach is to only load the ones you don't want.
uart(4) is a more recent serial driver and I believe it will supplant
sio(4) in time but I believe there are still some kludges that require
sio.

I'm glad you resolved your problems.
