Does that driver come with 10.3?  I cannot seem to load it and I don't
see it a tall and a I don't see a pkg search hit.  Do I have to compile
it manually?

From what I've been able to find on the internet, though, the trackapd
for this laptop is an ElanTech on i2c (I have only a vague idea what
that means).  I guess I should probably try to run OpenBSD on this
somehow to see what hardware it detects it as, though?
