FYI, you don't need the kernel options.  You just have to add the
following line to /boot/loader.conf:

hint.psm.0.flags="0x6000"

It is much easier for us to debug the issue.  Please revert the kernel
options and give us the following results.

1.  Test psm and moused without the above hint.
2.  Test psm and moused with "hint.psm.0.flags="0x2000".
3.  Test psm and moused with "hint.psm.0.flags="0x6000".
4.  Verbose dmesg output (for the touch pad model strings).

I believe you have Intel graphics, right?  Then, you need kib's KMS
patchset to make it happen.
