please provide your Xorg.log. this should be a clickpad, the matching
property should be set and the right button should be enabled in software.
not sure why it isn't in your case, but without the log it's hard to say
whether it's a bug or it's not recognised properly.

I don't think that there are the physical buttons, the capabilities property
only describes a left button so my guess is that the right button is
software-emulated based on the finger position.
