Fedora (Score 1)

I'm typing this from my 901 running Fedora 9.

It does not work (completely) out of the box; the things that you need to tweak are the following:

Boot Fedora from USB, by downloading any live iso (or the netinstall if you are short on space) and following http://fedoraproject.org/wiki/FedoraLiveCD/USBHowTo (or the relevant page in the manual: I'm frankly more happy with the manual)

Install the whole thing (SSD users might want to check out Theodore T'so blog on how to correctly format an SSD to have semi-decent performances)

See that it works "sort of"

Check out http://fedoraproject.org/wiki/Eee_PC. It does not have all the solutions but has valid pointers for googling.

The GMA950 is going to be a pain as usual, so if you plan to run compiz like I do you should google for optimizations of the driver.
It mostly boils down to inserting
Option "MigrationHeuristics" "greedy"
in the Device section of /etc/X11/xorg.conf but this might be outdated information.

However, this is to improve performances, the stuff will work (just slow, and compiz can REALLY slow down apps like Firefox)
