	Quoting the VESA 1.2 specs:

        AL == 4Fh:      Function is supported
        Al != 4Fh:      Function is not supported
        AH == 00h:      Function call successful
        AH == 01h:      Function call failed

	What do you think is wrong now? I still can't get the
"GetCurrentMode()" to return without an error.
