Yep, I'm seeing the same problem and yes the mouse goes totally ballistic,
moving around launches random stuff and whatnot. With 2.4-kernels the
situation goes away by switching away from X to another VT and then back
to X, not so on FC2-test. A collague of mine said it can be worked around
by giving kernel some mouse-related parameters at boot time, haven't had
yet time to investigate those myself.
