I had an Acer Aspire One, which I ran FreeBSD on. I got the webcam to work on it, so there should be no problem getting it to work with Linux.
My suggestion is you try the Ubuntu forums, upon failing that, try the Gentoo forums. I remember Gentoo had excellent forum support, and since it is still Linux, some of it may be applicable (i.e what kernel options you need [being Ubuntu they'd likely already be enabled] what drivers you need, and what programs to install).
