to get your keymap working, uncomment the lines under powermac in /etc/X11/XModmap and add "exec xmodmap /etc/X11/Xmodmap &" to your .xinitrc file. I emulate a three button mouse by passing "adb_buttons=103,55" to the kernel at boot (via quik or BootX) which uses the command key as button two and F11 as button three. You can modify these values to suit your needs. Note: This is using the FBDev xserver, XPmac is different, and can be changed on the command line, but I don't remember the particulars.
