right now doing a major renumbering and on a SS-20 have a QFE and a QE
card running in bridge mode...


# cat bridgename.bridge0
!echo "$if"
add hme0
add hme1
add hme2
add hme3
add qe0
add qe1
add qe2
add qe3
add le0


and it's working fine.    note that the up command must be issued at the
end for the bridge to be up (not just configured).

this is of course a mess in as much as you can't tell from upstream
which ip destinations are on which interface, but you can log in, read 
the arp table, and see who's on first.

don't know about your HP hardware, this is on Sparc.
