Right and middle mouse button do not work on clickpad

[Mason]

On my HP Pavilion DV6 laptop, using the beta2 of Ubuntu 12.04 (off a USB drive), the clickpad right button and middle button do not work--they report as "button 1" using xev.
These buttons both used to work back on Ubuntu 10.04 with the 2.6.32-32 kernel (see bug #826054 for more info).
I understand that the clickpad functionality has been removed from the kernel and added to x (xinput-synaptics), but the functionality appears to be only partial--only 1 button works!

Since clickpad support is advertised as one of the major new features for Precise, it would be nice if it worked correctly.
