buttons not working on mouse pad Dell XPS M1330

[dongle]

decided to get back into *nix, and i just got a dell
xps m1330 with Ubuntu from the factory with Hardy 8.04

everything was working great, then i loaded VirtualBox
and booted up windows XP and wanted to use the USB
inside the XP vm, so i found some info to edit
/etc/init.d/mountdevsubfs.sh to get the usb ports to
work in the XP vm

anyway long story as short as possible:

ran the command:
sudo gedit /etc/init.d/mountdevsubfs.sh

uncommented these options in the file:
#
	# Magic to make /proc/bus/usb work
	#
	mkdir -p /dev/bus/usb/.usbfs
	domount usbfs "" /dev/bus/usb/.usbfs
-obusmode=0700,devmode=0600,listmode=0644
	ln -s .usbfs/devices /dev/bus/usb/devices
	mount --rbind /dev/bus/usb /proc/bus/usb

HIT the SAVE button and the both buttons on my touch
pad stopped working, the touch pad still works, i can
scroll, double click all that but the buttons will not
work. I tried to put the # comments back and resave,
no luck....

I tried to use some of the gui mouse edit options and
turned the touch pad on/off and rebooted a few times,
nothing has worked so far....

Any ideas on where to go from here? I am thinking 
maybe to just rebuild from the dell rescue DVD that i
created with the built in tool before i started to
play...

I hope i can just edit some options to get my mouse
back though...

thanks
