Why not leave the choice to the BIOS writers? If some are able to save/restore video state by themselves, we shoudln't stop them. As long as the state after resume accepts setting the mode without lockup, we should be fine. >>2.

A live cd which boots, performs a few tests, displays the results on screen and offers an option to save these results to usbstick/network/disk/whatever. After saving the boot results, it will perform a S3 suspend and resume and display/save the results of that, too. If Intel have enough money, they could provide the functionality on a hard disk and it would have the benefit that S4 could be tested as well. If the disk has a FAT32 partition, the results can be saved there.
