Yeah. I don't really consider that a workaround... ;-)

I'm sure it does, but not for everything. I don't think dt uses printf
for much of anything. vi probably doesn't.

This is always the trade-off. If it doesn't go into -current, how much
do you think it will really be tested? Are enough people going to be
using it to test it well?

That's a question. I don't know. What if you are using a serial
console and Joe User who isn't in wheel logs into ttyp0 and runs a
homegrown program to draw fractals on the console (legitimately). ;-)
I'll let someone else talk about /dev/adb and /dev/grf stuff--this will
probably change with wscons.
