I have a Toshiba NB100-12N and netbook remix 9.04.

I was often experiencing a very sluggish launcher/screen refresh, and
after kernel updates from http://people.ubuntu.com/~apw/lp349314-jaunty/
I haven't experienced those problems anymore.

lspci after patch:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

Xorg.log after atch:
(II) intel(0): Attempting memory allocation with tiled buffers.
(II) intel(0): 0x00800000-0x00bfffff: depth buffer (4096 kB) X tiled
(II) intel(0): 0x00c00000-0x00ffffff: back buffer (4096 kB) X tiled
(II) intel(0): 0x01000000-0x013fffff: front buffer (4096 kB) X tiled

(II) intel(0): 0x01000000-0x013fffff: front buffer (4096 kB) X tiled

Ubuntu NBR now works great on my toshiba NB100-12N!
