problem with /dev/mouse

[Jeffery Lesh]

I installed and booted up fine.  Then ran OSX for a while.  Then back to 
YDL 2.3, but this time my boot partition had an error.  I ran fsck on it 
and fixed all the errors, now I have no /dev/mouse or /dev/usbmouse 
which makes it so that X doesn't run.  How do I recompile/initialize a 
device? I tried to reconfigure and compile the kernal using the "make 
oldconfig" command to use previous choices as default.  No luck there.  
Any ideas?

Thanks- Dundas
