Has anyone tried Ubuntu on the Toshiba Portege Z930?

So far I found only this page reporting success on all accounts using Arch Linux : http://www.linlap.com/wiki/toshiba+portege+z930

But I must say that's far from own experience so far. Regular Ubuntu has a lot of issues from which a few were fixed by updating to 3.5 kernel. Sleep also doesn't seem to work, results in kernel panic.
