Actually i've got a utillitie called `vidmode` that will let me change the VESA res on the fly.

So i'll have no luck with just a "generic VESA 2.0 kernel driver"?
And have to use one of the card specific drivers?
As for dosemu, do i need to specify anything if everything else is set up properly?
(BTW: Console VESA would be faster, since it's not emulated?)
Thanks.
