RME has some interesting information on its page
"FireWire Audio by RME - Technical Background "
http://www.rme-audio.de/english/techinfo/firewire_background.htm
I quote one section below and have added some URLs. Maybe some of these
companies can be convinced to create or support Open Source Linux drivers? (A
task for the Linux Audio Consortium!)

BridgeCo: used by M-Audio, Terratec, ESI, Edirol, Presonus, Apogee, Tascam.

Philips AV LLC: used by Motu
Might be this one:

Upcoming: a new chip from Texas Instruments, co-developed or supported by Echo.
Will be used in upcoming Echo and Mackie FireWire devices.
?

Upcoming: a new chip from TC, called Dice II. A few years ago TC have bought a
company that produced non-audio FireWire chips. Now this chip, announced to be
available more than a year ago, is said to finally arrive. If so, it will be
used in upcoming TC FireWire audio interfaces for sure.

Upcoming: a chip from Oxford Semiconductors called OXFW970. Seems that this is
the chip used in Apple's just announced 'GarageBand' FW interface. It is said to
be very cheap and might cause another flood of very cheap FW audio interfaces in
2005.
