Hmm... The above is a bit of speculation and it solely dependent upon the BIOS implementation. We could change the X server to make VM86 call to set the vga resolution or the call could be issue from the console driver and it will save a lot of headaches;additionally we could provide and option to use the current mode setting in the X server for those rare exquisite moments in which someone wants to play with vga sync parameters ... Now all what we need is the VM86 call :) Amancio
