As far as I know, not only the VGA driver does not do any mode
switching, even the VESA one doesn't (because the protected mode
interface doesn't cover the mode switching functions as far as I
remember). Only the video board specific frame buffer drivers are able
to switch modes, and the bad thing (for me personally) is that even in
2.6.12 there still is no (64-bit) support for the i915 chipset. So I
continue to be required to live with the video mode that XEN 'sets'
prior to loading dom0, and short of it supporting a VESA console my
first minimal attempt was to at least increase (and propagate) the size
to the maximum possible without significant changes.
