I cannot say whether it's a "solution" or "workaround". If I had the
WinXPPro installed that was shipped with the laptop I could figure
out... Maybe that's the behaviour of the BIOS to hide the touchpad
from the OS if a USB mouse is plugged in. Wait, my girlfriend had an
IBM-laptop and depending on when she plugged the PS/2 mouse either
both (trackpin + mouse) or just the mouse worked in Windows2k... It
was an older model, maybe X series. Cannot tell right now...

My hotplug is deactivated as I don't need it. But I _think_ it should
not matter if it is used (untested).
