I believe that your system has "Intel 3000" graphics. If so, you are
out of luck unless you
are willing to play with hte very early development KMS code that kib
is working on under a grant from the FreeBSD Foundation.
http://wiki.freebsd.org/Intel_GPU

This is a non-trivial thing to install and is NOT full-featured at this point.

Should be settable from BIOS. F1 at boot and look through the options
for the option to disable the trackpad. It's about the first thing I
do when I get a new system.

Requires KMS which is in alpha, but is reported as working. The
discussion of this work
is taking place on freebsd-x11 at .

Sorry. No idea on this.

There has been discussion of this chip on freebsd-wireless@, I don't
think a driver is
yet available, but there is quite a bit of interest, so it may be coming.

Good luck. Getting recent laptops working with FreeBSD is certainly a
challenge. On my T520 I'm still running VESA and waiting delivery of
an over-priced Intel Wireless card with
the custom PCI ID Lenovo requires. (Standard Intel 6205 is $20 while
the same card
with the Lenovo PCI ID (FRU 60Y3253) seems to run $100-$145.
