Everything worked great for me, cept my version was really slimmed down. I am using a 7330gz laptop.
Anyways, what I suggest is looking for a better touchpad driver or getting a mouse for now. As far as the volume wheel, more than likely there are no drivers yet, so to see if the sound card works, look for a software based volume adjuster. If you can't seem to get it to work, then there are two ways to see if works:
1) Check the dmesg file for sound card errors during bootup.
2) Check
www.alsa-project.org to see if your sound card is supported.
If you aren't sure sound card you have, boot into Windows, (if you still got it.) Click Start, right click on My Computer, click Properties, click the Hardware tab.
Now click Device Manager and look for Sound, Video, and Game Controllers. Your sound card is listed under there.
Hope this helps ya!
