It needs several things. Recent xorgwizard, modesetting driver in alternate location and kernel where poulsbo stub driver has been disabled and intel gma grahics driver has been included. As you know, the name of that kernel driver vary depending of the kernel version.

In recent kernels it is /lib/modules/3.8.4-upup/kernel/drivers/gpu/drm/gma500/gma500_gfx.ko

Putting it simply. Try some of the suggested Puppies in above thread. They have the support oob.

Saluki 3.2 kernel does not have gma500_gfx ?


3.5.0-KRG-iCore2-smp-pae-srv1000gz has it
But it loads while X is running but apparently isn' t needed on my G33 .


*

If gma500_gfx does not work : /usr/bin/915resulution is or was used in former Puppies to switch the resolution to widescreen . But the 915resolution does not read a data file like lsusb or lspci . Chip data is compiled into the binary . tempestous was very good at adjusting/patching the 915resolution.c with the data forn newer intel chips . That needs to have the lspci -nn output to add the correct

915resolution.c wrote:
case 0x27ac8086:
type = CT_945GME;
break;


lines into it .

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.
