I'm submitting the following self-review case on my own behalf.
I believe it is merely an obvious extension of already delivered
architecture, and therefore qualifies for self review.

4. Technical Description
Title: Delivery of audiots for x86
Requested Binding: Patch
Problem:
Some southbridges (most commonly used with AMD processors)
use an ALi M5451 south bridge and AC'97 audio controller.
There is no support for these in Solaris today.
Solution:
We already have a driver for this part -- audiots commonly
used on SPARC systems. As part of Boomer (2008/318) I've
already made changes to the driver to ensure it will work
properly on x86 processors -- and this has been verified by
testing this driver on such x86/amd platforms by 4Front.
So, we will simply deliver the audiots driver on x86 platforms.
While it would be "cleaner" for audiots to be in its own package,
the SPARC platform already delivers this in SUNWaudd. Rather than
have different packages for SPARC vs. x86, we will simply add
this driver to the x86 SUNWaudd package.
While this case is seeking patch binding, we have no plans to
deliver the recompiled binary for Solaris 10 or earlier. We
don't believe there is any architectural reason such a backport
should be architecturally significant though -- the audiots
driver using the legacy SADA interfaces should support x86 just
as well, with only minor, if any, changes to it.
