The drivers themselves are not Boomer versions, nor can they coexist on
Boomer. The changes referred to relate to the "protocol" for dealing
with /dev/mixer -- the old OSS applications would not be compatible with
Boomer due to some security enforcements that Boomer makes (required for
Zones). This was discussed at length with 4Front, and they agreed to
the changes.
Basically, the change is that you can't touch or retrieve values
relating to a specific device by accessing an anonymous device.
Instead, you have to open a specific device node *just* for this
device. You *can* however access the list of real devices using the
anonymous device. (So generic "/dev/mixer" is only good for device
enumeration in Boomer. For real mixer device control you have to access
the mixer device node reported by the enumeration API.)
