Well, I have a program called TiLP that connects through a USB cable to 
a Ti83+ calculator, which I use in calculus class. I have a linking 
program to use under windows, but I have been unable to get the linux 
link program to work. I was told it is because the 2.6 kernel detects 
USB devices differently, so I thought I would try the 2.4.

That seems like a lot of work, so I will just install the 2.4 kernel and 
edit the xorg.conf. Then if the program doesn't work in 2.4 either, I 
can quickly switch back to 2.6 settings.
