VGA compatible controller: Intel Corporation Atom Processor D2xxx Integrated Graphics Controller (rev 09)
I was wondering if anyone could help me with any suggested solutions or workarounds?
I think a solution is difficult because I am not sure if the drivers (yet) exist. I read elsewhere that the 3.3.0 kernel would support the Cedar Trail. I’ve installed the 3.3.0 kernel from Experimental which seems to run fine but that does not to affect the launching of X as far as I can tell. I am not sure if I would have to load some extra kernel modules or something to get it working; but I can’t find any documentation about what they would be.
In terms of a workaround, I was wondering if it is possible to put VESA into a 1024 x 768 resolution?
At the moment, it is not loading with any flexibility. xrandr reports:

I also tried adding vga=712 and vga=0x318 manually to the boot parameters in grub since these should be the codes for 1028x768 VESA but without success.
In addition to the /var/log/Xorg.0.log log the only other problem that I have seen is that if I try to automatically recreate the Xorg.conf file by killing the display manager and running X -configure it fails with this error:

(EE) open /dev/fd0: No such file or directory
Would anyone be able to help me with these problems, either for a solution or a workaround to get the resolution up to scratch?
Many thanks!
