I'm trying to run XF86 4.0.2 on NetBSD/i386 1.5.1_ALPHA and having
a few problems.

I can run startx and bring up a session with no problem, but my
mouse pointer moves randomly, mainly at the top right corner.

I've made sure that "Protocol" is "wsmouse" and the Devices is
"/dev/wsmouse0". wsmouse0 shows up in dmesg

[snip]
pckbc0: using irq 1 for kbd slot
wskbd0 at pckbd0: console keyboard, using wsdisplay0
pmsi0 at pckbc0 (aux slot)
pckbc0: using irq 12 for aux slot
wsmouse0 at pmsi0 mux 0
[snip]
wsmux1: connecting to wsdisplay0

(I can send the full dmesg if anyone would like it).

Anyway, any suggestions would be appreciated and put to the test.

Regards
Nigel
