Mark Weaver has pointed out a serious problem with NetBSD-1.4.x on the
Macintosh TV. The problem is that adb_direct only works on his MacTV
if the Booter dialog is used to force the machine type to "80", that
is, to a Performa 550 (a sister model).

Although this is likely an egrerious bug, the possibility remains that
there are _two_ types of MacTV, so that fixing this would break NetBSD
on the other type. So let me ask, is there _anyone_ _else_ using a
MacTV with a 1.4.x GENERIC or other adb_direct kernel, or who would be
willing to test an adb_direct kernel?
