Screen was assuming setting a 800x600 mode would work anyway, but currently the Intel driver only supports the 'native' mode for laptop panels. Added a 'strict' parameter to SetBestMode which, if true, fails if it doesn't find any mode with the passed width. If false, and can't find any good mode, just uses the first mode in the list (could be improved). This fixes bug #2350
