I didn't try the first version of your patch, so my first question is: is
this patch sufficient by itself ?

Any my results on NetBSD/mac68k - current of 12 Apr 1998 is that the boot
completes, but the boot messages stop after the asc0 line.

The intvid lines are not printed on the screen, but are present in the
dmesg output.

The text is white on black background (as usual in this screen resolution),
but after a while some of the white pixels become black.

X starts, but the black part of the screen remains black. If I move the
cursor around, I can paint the remainder of the white pixels black.

Other than this the machine boots completely, and it is accesible on my
LAN (allowing me to send this message from a telnet session).

I'll revert this patch for this time :-)
