Is this the linux mouse driver or the X11 mouse driver? The linux mouse 
driver has to accept the calls and forwards it to the X11 mouse driver.

Under X11, the mouse-events the X11 server receives from the linux 
mousedriver must be passed on to the window manager. Finally, this 
windowmanager can handle the mouse-events itself or pass it on to the 
applications.

there are X11 based tools that can monitor the X11 events. With them you 
can see if the events come to the other side. I donnot know if vnc has 
monitor options for these events. I see you have xev, that's such a tool.

Then you have bad luck. Keep in mind that Xvnc (the binary called from 
the vncserver script) is a limited X11 server by itself. Actually, it is 
not limited as an X11 server but I can tell you, it has not much 
optional items available.

That's bad luck. You can try if on of the vnc-alternatives (tight-vnc, 
true-vnc,...) does provide  more than 5 buttons.
