Another option could be to just have a shell script that will rename intel_drv.so to something that xorg won't find. We have had multiple builds of ati and intel installed at the same time that needed to be renamed to pick the one you wanted. > I also found similar problems in "radeon", but found that > modesetting would somehow pick a display mode that the monitor > didn't support.

One reason for using radeon is that it will make use of 2D hardware on older cards, newer ones are 3D only. > But maybe modesetting is mature enough (and intel bad enough) > to warrant being the default for Intel GPUs. I don't have a feel for which generations of Intel GPU have 2D or video HW. What Mesa settings are you using with all of this?
