I've posted the webrev for audiovia97. This was covered by PSARC 2009/321. This is a driver for older Via 82C686 south bridges, used with 32-bit Via C3 and Pentium-III class processors.
The driver was written by 4Front (apparently building upon other Boomer work I've done). All I've done for this is simple packaging, cstyle fixes, and integration.
Let me know if you want early access to binaries! (You'll need Boomer or build 115 or later installed to use it.)
