Salvio, I've done a fresh install of Fedora Core 1 on a Dell Latitude C600 (GRUB dual boot with Win98). I was running RH9,which seem to worked quite fine. I've had many of the same problems since installing FC1 as you have described in a few previous threads: ---conflict between mouse and PCMCIA card (fixed that with Kai's suggestion to you, i.e., acpi=on in grub boot) ---with "acpi=on" shutdown doesn't work completely. It appears to go through the whole shutdown process, but hangs with a blank screen after "power down". I haven't seen a solution posted that works for me. ---with "acpi=on" USB mouse movement is jerky for me as well. I keep a System Monitor applet on my panel and noticed regular spikes in processor activity, which I correlated to the Battery Charge Monitor applet (battstat-applet-2). I removed this applet from my panel and mouse movement is no longer jerky. Don't know why this works (something to do with acpi, probably). This is not really a good solution since you can't monitor the battery charge, but I will use it until I find a true fix. ---The mouse configuration that has worked well for me is "ALPS GlidePoint (PS/2)" with "Emulate 3 button click" checked. (I saw this solution suggested somewhere on the net; don't remember by whom). I can use my touchpad just fine with or without my USB mouse plugged in (Microsoft wheel mouse, infrared, wireless; or Kensington wheel mouse). I'm still quite the newbie (just started using Linux/RH9 in September), and don't know much technically, but I hope the above are helpful or at least send you down the right track to the right solutions.
