serio chaining in 2.6.x?

serio chaining in 2.6.x?

[Zinx Verituse]

I have a device (the device in question is the infamous cuecat) which
connects between the computer and a PS/2 device, and I'm trying to
figure out a good way to chain serio devices, such as:
	atkbd <-> cuecat <-> lowlevel driver

The serio driver, however, is very clearly not designed for such
chaining.  So, the question is:

What do you folks think the best method for chaining the
serio drivers is?

You grab the port. Then you create a new one and register it. And you
forward all data that's not destined for you through to the new serio
port.

Many thanks -- I hadn't considered creating a new port, and I'm sure this
solution will work perfectly :)

Unfortunately, I hit a snag...  I can't see a way to rescan or
disconnect all the ports that need intercepted (or, indeed, any of
them that are already connected)

Suggestions welcome :)
