Skype (video) works out of the box .. built in mic doesn't, but it's an easy fix .. it's all in the Peppermint tutorial here:
http://linuxforums.org.uk/index.php?topic=9782.0If you'd rather have a go at compiling acerhdf 0.5.27 let me know and I'll post instructions .. it's quite easy .. and don't worry about asking for help, that's what the forum is for

[EDIT]
Is both necessary, might it work just with a new acerhdf?
I'm going to "guess" that just updating acerhdf would work, but it's only a guess .. certainly can't hurt to try.
I have to "make/compile" the new acerhdf, how?
OK, instructions for installing acerhdf 0.5.27 ..
first you'll need to install the
linux-headers-generic and
build-essential packages, so open a terminal and enter:
sudo apt-get install linux-headers-generic build-essential
hit enter, and enter your password when asked (be aware, you won't see anything whilst you are entering your password, but it is going in).
when that command finishes, enter:
and hit enter.
Then to download the acerhdf tarball enter:
wget "http://www.piie.net/files/acerhdf_kmod-0.5.27.tar.gz"
and hit enter.
To unpack the tarball, enter:
tar -xvf acerhdf_kmod-0.5.27.tar.gz
and hit enter.
Now change to the acerhdf_kmod directory with:
and hit enter
Now to build and install acerhdf 0.5.27, enter:
make && sudo make install
hit enter, and enter your password when asked.
Now REBOOT.
Once rebooted, open a terminal and run:
and hit enter .. you should get something similar to-
[ 10.144202] acerhdf: Acer Aspire One Fan driver, v.0.5.27
If you get version 0.5.27 .. check if it now controls your fan as it should.
