I have some information to share on the A30-141 here is the link:

Hopefully we could somehow figure out how to fix the ACPI.

Also the (AMR) ATI AC97 Modem inside this laptop, which I believe may be
used in current/future models has a modem driver being developed for it
now. ALSA are developing and I am testing. I will keep you posted on
the progress.
