On my mini10v I have current have osx, and linux. Pretty similar setup to you actually - using the grub loader to boot linux - i guess there is no easier way.
Anyways I wanted to know is the chromium build you use the newest? or most compatible for the mini 10v? Is there a particular guide you used to install it?
PS- how is your performance on youtube videos? because its very choppy for me, and I was curious if it was something more internal rather than just the slowness of the Atom cpu as a whole.
