I'm guessing that something with the Xorg 7.4 update has broken the 
mouse support on your system. Can you try this? Leave the mouse plugged 
in, and start the install CD. At the boot splash-screen, try the option 
for "Boot to emergency console" (6 i think). When the console comes up, 
try moving your mouse around, if moused is working, it should show a 
cursor at the console menu.

If the mouse works at the console, then lets see if we can fix Xorg. Go 
to the shell prompt via the emergency menu, and edit /etc/X11/xorg.conf

Look for this section:

Section "ServerFlags"
         Option "DisableVidModeExtension" "True"
         Option "AutoAddDevices" "False"
         Option "AllowEmptyInput" "Off"
         #Option "NoTrapSignals"  "True"
         #Option "DisableModInDev"  "True"

Comment out the two middle options:

Section "ServerFlags"
         Option "DisableVidModeExtension" "True"
         #Option "AutoAddDevices" "False"
         #Option "AllowEmptyInput" "Off"
         #Option "NoTrapSignals"  "True"
         #Option "DisableModInDev"  "True"

Then run the command "startx" and it should bring up the installer GUI. 
If disabling those options brings back your mouse, please let me know. 
They are setup the way they are right now because when moving to Xorg 
7.4, they caused some problems with various systems, but in your case 
maybe they are needed.
