Do you mean the "scfb" driver, instead of the intel one? I haven't managed to make it work, but didn't try very hard. I read it was unaccelerated, and I have already vesa that suits all my non-accelerated needs, so I still wonder what would be the point of scfb in my particular situation. It doesn't seem to be present on the CFT image, because when I removed all xorg conf, it showed exactly the same symptoms as my SNA testing, so I guess (at least on the CFT image) X defaults to intel driver with SNA acceleration. Thanks for the help, Natasha
