Charlie6 had that kind problem also. You could post or pm him about how he solved the problem.
This is the post I got concerning intel brookdale graphics. His fix might help, not sure though:
i have tested the attached pet which i now submit to you for eventual integration in a next update of exprimo, as a brookdale fix (brookdale users are so many ... Wink ). It works with 5X15 and 5X3.4.2.
It is intended to substute the 2.11.0 xorg intel_drv.so to the already present 2.13.0; that's the way the /usr/sbin/BROOKDALE script is edited. I also tested that -imho - changes in xorg.conf's Section Devices Options have no effect.
I install it after bootup, once X has started, after quick setup settings, and - important - whitout restarting X. At that time, i start Xorgwizard to allow the Brookdale detection, and driver substitution. That's the reason why it would be better to integrate it inside the puppy-squeezeXXXX.sfs.
Please note the BROOKDALE script looks rather rough.
Hope this helps brookdale owners...
