Hi!
I've successfully installed Vl in my Acer Aspire One . Pretty straightforward.
The only 'problem' I had is ethernet not working pretty well, but as wireless is configured out of the box, who wants wired net in those little netbooks

.
Btw, I'm sure you can configure it without much troubles, I just haven't dug enough.
To install vl I chose hosted install, and installing archlinux first in another partition. Wanna see how?

HTH
