I found a spec for the "Allegro-1", and there's a FreeBSD driver that handles
the Allegro and Maestro3.

is good enough that I was able to use it to figure out how to enable legacy

Mine says:
vendor 0x125d product 0x1988 (audio multimedia, revision 0x12) at pci0 dev 8 function 0 not configured
vendor 0x125d product 0x1989 (miscellaneous communications, revision 0x12) at pci0 dev 8 function 1 not configured

but if I use the maestro3 driver under FreeBSD, it probes successfully.
