Negligable, less than 1k i would guess. As for performance gain due to
shorter console handler: i would be surprised if you could even get a
meaningful measurement.

I would even go in the other direction and add a procfs entry
(presumably /proc/sys/dev/tty/blank or something similar) in order to
supplement the IOCTL mechanismn which applies just to the selected tty,
while SYSCTL/PROCFS would apply to the driver = all tty's to be opened
during runtime.
