We talked with malc briefly on irc yesterday, and this is what he gave me: http://cvs.savannah.gnu.org/viewvc/vgabios/vbe.c?root=vgabios&r1=1.47&r2=1.48 this is not the test case but the missing support he's referring to. It appears the patch implements just 2 functions which both just does int10, so should be easy to implement in seabios, but my knowlege isn's sufficient to do that (it needs some asm coding). Thanks, /mjt
