I've tried compiling bt3c driver and bt support for hpcarm.
Unfourtunetly compilation fails with

cc1: warnings being treated as errors
/usr/src/sys/netbt/hci_event.c: In function 'hci_cmd_read_bdaddr':
/usr/src/sys/netbt/hci_event.c:605: warning: implicit declaration of
function 'splraiseipl'

Looks hpcarm is missing splraiseipl. This 3com card 3CRWB6096 have
pocketpc 2002 drivers that should work under HPC 2000 after small cabs
and dlls hacks. I don't have card yet but with netbsd support it could
be graet expansion for Jornada.
