Fixed by now.

How ? There are quite a lot of ways to solve the two-consoles-which-are-
really-the-same problem, some of them just aren't very clean. (Probably
the cleanest is to merge arch/parisc/kernel/pdc_cons.c and drivers/video/
iodccon.c into one file).

This was there before, wasn't it ?

Sure it would, and I encourage everyone with a box using serial console to
clean up drivers/char/serial.c (it already should do everything you want,
it's just not clean) and use that. The problem is there are boxes with
graphical consoles as well.

Where's the patch ;) ?
