Asus EEE 1225C can boot correctly and start a X session only if you put 
i915.modeset=0
in Grub kernel line. Otherwise you will get a black screen.

===lspci output===
00:02.0 VGA compatible controller: Intel Corporation Atom Processor D2xxx/N2xxx
Integrated Graphics Controller (rev 09)

===Additional infos===
Using kernel flag
i915.modeset=0
solved the problem only for a few boots. After that the system experienced
again troubles.
On a forum, a user told me he had the same problem and he solved by closing
laptop lid, waiting for computer suspension and then resuming the machine. It's
crazy but it works! The user also said that he experienced this problem only on
64bit Fedora, and he says that 32 bit Fedora works fine...
