I do consider it trivial for now as the only thing that user can do is
"echo" desired driver into serioX/driver to rebind it. The typical node
looks like this:

[dtor@core dtor]$ ls -la /sys/bus/serio/devices/serio0/
total 0
-r--r--r--    1 root     root         4096 Jun 17 21:49 description

description 	- i8042 Aux Port
driver		- psmouse
legacy_position	- isa0060/serio1 (take from serio's phys, can be used
to match with /proc/bus/input/devices).

Every driver will have a set of custom attributes that will be documented
on one by one basis. Btw, where would you document it? Documentation
directory entry? Something else?
