Hey, I’ve just installed Ubuntu Netbook Remix 9.04beta daily build (.img file dated April 4, 2009). Here is the link to daily-live/current. It might change, of course. Not link, but .img file.
When tried previously, with alphas and previous beta builds, didn’t have luck with wireless and touchpad. Wifi didn’t work, and touchpad was flaky.
I have to report that today everything works without tweaking. Will test further and post it here.
