First, on the audio side, I have been working on driver support for the audio on your system. I recently checked in a patch that others claim works quite well (I don't have a system to test with). To use my patch, you need to download alsa-driver-1.0.14rc2 from alsa-project.org, and download my patch from here
. Instructions are here
Send me an email, and I will add you to my mailing list for future driver patches.
As to the acpi issue, here
is a link some of my testers reported that helped.
