If the X server is not using DRI, the BIOS initialisation is mostly
sufficient, as X resets the correct video mode when one VT switches
back. However, if one is using DRI, the BIOS initialisation is OFTEN
not even close, so you have to do something like I did to the Radeon
drivers: http://cpbotha.net/dri_resume.html
My changes do a re-initialisation of card-hardware every VT switch.
