Avendo tempo ho fatto una googlata, spero ti torni utile.
Seguendo la traccia di una distro modificata da un utente sono finito in questo annuncio ufficiale del team Ubuntu:
"GMA500_GFX driver
With kernel 2.6.39, a new psb_gfx module appeared in the kernel source developed by Alan Cox to support Poulsbo hardware.
As of kernel 3.3.rc1 the driver has left staging and been renamed gma500_gfx and is thus the default, supported driver for Ubuntu 12.04 and higher.
Starting with kernel 3.3.4 , the gma500_gfx driver works without adding any boot options.
The gma500_gfx does not (yet) support 3d graphics and it is unclear if it will in the future."
