Yeah, use evdev.  So much better!  All the buttons are there, and evdev
works with hotplugged mice.  I use it with my Bluetooth mouse and with
USB mice on my laptop.

This is what I added to xorg.conf for mine.  (And then you add EvMouse
as an input device in the ServerLayout.)

Section "InputDevice"
        Identifier  "EvMouse"
        Driver      "evdev"
        Option      "evBits" "+0-2 -3"

The evBits tells the driver what capability bits to match on.  That's
how it knows what's a mouse and what isn't.  This reads the value that
you can see in /sys/class/input/input*/capabilities/ev

I don't know anything about revoco.  I use xbindkeys and xvkbd to handle
browser back/forward and window close on some of the other buttons.

As for glossy surfaces, I have found that the newer laser mice seem to
work on anything.  Other than that, mouse pads still work, and generally
give a smoother glide than a desktop.
