OK, here's a good question for all of you who have tried (probably out of
absolute necessity) using the serial console feature of NetBSD/Mac:
If I boot up with serial console on a system that has supported video,
will my grf0 device get properly configured?
Why would I want to use serial console if normal video (and, by
implication, the ite internal console)? Well, I'm struggling with Taras's
video_lkm code, trying to get it to work on my accellerated E-Machines
Futura-SX graphics card. Somewhere during the OpenDriver code, the card
takes over the display, blanks it out, and I can't see any more debug
printf() output from the lkm code! Makes it pretty hard to debug...
So, I'm planning on booting up (single-user) with the serial console so I
can still see my debug messages when the screen goes south.
