Hi,
I don't know how well this is an answer to your question,
but I would like to be able to find a list of registered "consoles,"
whether they be serial, usbserial, netconsole, lp, or whatever.
/proc/tty/drivers does that partially.

I have a patch that also does it in /proc/consoles:
  http://www.xenotime.net/linux/patches/consoles-list.patch
Is somewhere in /sys the right place to find a list of all consoles?

Thanks,
