I have a Fujitsu U820 aka U2010, a lovely ultraportable, with a nice Atom Z530 processor in it. The only shame was the use of GMA500. I had the pre-unity Ubuntu Netbook remix for a long time on it with LXDE and it worked well, I didn't upgrade because I had to stick with a kernel where someone had put in a lot of effort to get the official drivers that came via Intel to work reliably.
Eventually bit-rot set in and I had to upgrade, but the newer kernel and GMA500 driver was never as good, it wasn't much better than a VESA driver really.

So I am really hoping that there will be good useable driver and I can breathe some life back into what is still quite a nice device.
