I have been going around in circles with this for a while trying to get
my clickpad initialised to work with extended w mode. I don't have it
right but I have noticed if I boot windows or fedora and then reboot to
netbsd I have extended_w. Doing this I have multi-finger working so you
can hold down a button and scroll though a menu with the other finger.
This patch also provides 3 button emulation for a click pad. There are
some sysctls that set the size of the mouse button regions (height and
left, middle and right button regions). I am putting this out there
just in case it works for others and the initialisation issue is just my
hardware. Even if extended_w does not work it does at least mean that
click pads will have 3 buttons and you can scroll a little bit by moving
the finger that has activated the button (I have been surviving like
this for quite some time). Any comments/improvements welcome....
