Ah, but where's the bug? In the kernel or the X server?

I think that it is in there somewhere, I know that there are probably
quite a few references to it, anyway. Back when I started running NetBSD,
it was pretty much necessary (no X, and my machine had the scrolling ADB
problem, so the console was pretty much useless for me ;-)

:-)
