I tried it, and it seems to get really confused - constant stream of seemingly random error messages.

No data at all from it.

No.

It doesn't say No such device, it just hangs, giving no data for the trackball, but works fine for the generic mouse.

Yes, it does the same as /dev/psaux

I: Bus=0011 Vendor=0002 Product=0001 Version=0000
N: Name="PS/2 Generic Mouse"
P: Phys=isa0060/serio1/input0
H: Handlers=mouse0
B: EV=7
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=3

That's for both the generic mouse and the trackball.
