Is it possible to have more than one pointer device?

[CMonster]

Well, is it possible to have more than one pointer device in Linux?

Specifically (for a laptop), is it possible to write an XF86Config-4 pointer device entry that will allow to use either the touchpad or a USB mouse without having to restart X with a different config file?

I remember a Windows box that had I a PS2 and USB mouse that you could use either and it would just pick up the cursor from where the other left off.

It will be possible to setup both a USB and PS/2 device. I have that setup with PS/2 (Trackball) and Serial (Glidepoint).
