Hi...
Came back to the office tonight figuring to clean up my
mods to pcvt_drv.c, and then check out syscons.c, and figured out that
syscons.c already has devfs support in it *sigh* And all that work I
went to trying to figure out how to do it, and I could have just copied
the syscons stuff :(
Ah well, a learning experience :)
Well, here is a context diff of the changes I made to pcvt_drv.c
in order that the ttyv* devices get created properly in devfs, so that
you can use devfs on a system with pcvt. If someone can check it over,
and commit it to the tree? Or tell me I really don't know what I'm doing?
