This is an interesting little problem. I'm trying to get the Z50 mouse
driver working on a 1.6B kernel (which runs all of my 1.5.2 binaries, so
-- and yes, I know I should compile a new userland to go with it -- I'm
not too terribly worried about it. I'm only using 1.6B because my NIC
works with it, and doesn't work at all with 1.5.2).

The appropriate configuration lines from my 1.5.2 kernel, with a working
trackpoint driver are:

vrdsiu* at vrip? addr 0x0b0001a0 size 0x20 intr 21
wsmouse*        at      vrdsiu? mux 0

The corresponding lines from the 1.6B kernel (with a non-working
trackpoint) are:

vrdsiu_mouse* at vr4102ip? addr 0x0b0001a0 size 0x20
wsmouse*        at      vrdsiu_mouse? mux 0

'dmesg' on the machine reports:

vrdsiu_mouse0 at vr4102ip0 addr 0xb0001a0-01bf: can't map interrupt line

Adding a 'intr 21' to the end of the 'vrdsiu_mouse*' line gets me an error
of 'extraneous locator: intr'.

Any solutions?
