Micro Innovations Mouse, Side Buttons not Responding
 

I just got a 5 Button Micro Innovations Cordless Optical Mouse(PS/2) and hooked it up to my Gentoo Box. So, according to everything I've read I need to tell Xorg that it's a 7 button so my mouse section is thus:

Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/mouse"
Option "Buttons" "7"
Options "ZAxisMapping" "6 7"

At first when I reload X my scroll doesn't work so I run xmodmap -e "pointer = 1 2 3 6 7 4 5"
Now my scroll button works, but when I load xev and test my buttons, there is no response at all to me pressing either of the side buttons. I get a response from the top buttons including the wheel and the wheel-button, but... yeah...

Any help would be appreciated, thanx.

PS. Everything I've found so far just tells me to configure it exactly how I have it configured...

PPS. I've also tried setting "Protocol" to "ExplorerPS/2" which has absolutely no effect.
