Hello,
i needed a new, power-saving, affordable netbook and decided to get this
one with Intel Atom N2600 integrated graphics (GMA 3600 aka PowerVR SGX
545(unfortunately)).

:~$ lspci
[...]
00:02.0 VGA compatible controller: Intel Corporation Cedarview
Integrated Graphics Controller (rev 09)
[...]

after building a vanilla kernel 3.4.6 with experimental gma500 and
gma3600 support enabled most things for everyday use are working.
After adding
GRUB_CMDLINE_LINUX="acpi_backlight=vendor acpi_osi=Linux"
to /etc/default/grub
i can change the backlight, and after
:# touch /etc/pm/sleep.d/99video
i can properly resume from suspend, but thaw from hibernate doesn't
reset the video properly (black screen with garbled cursor).
Also, the only Fn keys working are the ones for brightness and suspend.
Any help appreciated.
