No Mouse: Urgent

I was having troubling with my laptop's touchpad acting wierd (over-reacting to my movements), so I went into setting and changed it from PS/2 to Serial. Then the new kernel fizzled, so I booted back to the old one and changed back the mouse, but it still won't work. And yes, the mouse worked fine under the old kernel (I'm under it now).

Edit: This has been fixed. I deleted the mouse from the configuration file for X and Kudzu reinstalled it properly. Huzzah!
