Probably not.  1280x768 is not a standard vesa mode, so there is no
identifier for it.  It is possible though that the BIOS has an OEM id for
it.

Try scanning for the id.  Use vga=ask in your boot parameter.  Then
try each modes until you get the desired resolution.  If not, then you
have to use intelfb.
