Hi Peter,
I was finally able to get some time to recompile the various RPMs for F21 with the patches applied and test out the whole stack.  I used the first iteration of the kernel patches posted to the mailing list, but it looks like those might change a little bit; either way, they work even if they're not the final version.

Aside from the issue below, the trackpoint buttons work as expected.
Setting TouchpadOff=1 disables the touchpad for moving the cursor, but
the clickpad buttons are still enabled.  This seems to be the intended
behavior based on synaptics(4), so I can live with it.

The X11 stack seems to work fine, but the hwdb entry is not tagging the
device properly.  By removing the "MatchTag" option from the xorg.conf.d
file, everything worked as expected.  For the hwdb update, I dropped the
file in place and updated.  Here is verification that the hwdb piece is
in place but not working:

[root@x1 ~]# grep -v ^# /lib/udev/hwdb.d/70-touchpad.hwdb; udevadm
trigger /dev/input/event5; udevadm info /dev/input/event5
