audiocmi driver [PSARC/2009/263 FastTrack timeout 05/06/2009]

[Garrett D'Amore]

It looks like I never indicated one way or the other, but I'll not be 
delivering SPARC support for these devices, for the simple reason that 
the systems I have access to are not power-compatible with the card I 
have available.  (Specifically, the card seems to require 3.3V power, 
but is not 66MHz capable.  The SPARC systems with 32-bit/33MHz slots 
only provide 5V power to such slots.)

If anyone has any questions or concerns about this, please let me know.
