I realized there was a possibly significant gap in my knowledge of hardware, so I
searched, and found that there have been a few Firewire devices with both audio and MIDI.
The questions I have are (a) are any of them known to work well with current Linux, and
(b) how is the MIDI supported on the backend, is it ALSA?

Jack and jack, both audio and midi. There are rumours of alsa drivers, but
so far as I know they are not there. If you must use it with alsa midi,
start with a2jmidid and use "MIDI Through" if you must. So long as the
application that uses alsa makes some alsa ports you can do all your
connects in jack midi with a2jmidid. But if the app just looks at alsa and
connects direct use the through as well.

i have used focusrite sapphires with good success, both the now
discontinued pro26 and the pro56. FFADO makes midi available as a
jackmidi port, so (as others have noted) you will need to run aj2midid
-e to bridge them to ALSA sequencer clients. i just added it as a
post-startup command in qjackctl and forgot about it.
can't comment on MIDI timing performance, i only ever used it for
controllers, but i don't see any reason to have doubts.

I use Roland FA-66 with no troubles at all.

One of the great things about Firewire Audio is the iso-synchronous
protocol that is used there. Audio + Midi are sent in the same
data-stream, interleaved.
As opposed to most PCI and USB sound-cards firewire midi is not a
separated on the bus or data-link level.
It still depends on what the hardware does but everything starting at
the firewire-end all the way up to jack-midi can be in perfect sync,
zero jitter, identical latency as audio.
