Ah, well, nobody pointed this out.

Nobody pointed this out, either. Modular xorg was a patchwork for a
while and it took some doing to get it working. At the same time x11 was
kind of abandoned and so was non-modular xorg. At least that's what it
seemed like to this user.

Because I didn't know where the link came from and nobody sent out a
"heads up for this problem" email. It was probably discussed on the
SECRET CORE MAILING-LIST if anywhere.

Yes, this is true. However, this wasn't documented anywhere in current
or release.

I know. That's what I get for using -current, but the reason I use
netbsd is the documentation.
