No magic wand, I'm afraid, but I am running a very similar setup to you.

Inspiron 5100 lappie running XP Pro; 1500sc server running Mandriva 2007.0,
Cybex 4-port KVM, Logitech wireless wheelie mouse. The whole setup works
flawlessly here.

Not a "known issue" with Linux AFAICT, but our only major difference is the
KVM. Since you saw this with SUSE also, and given that re-plugging the mouse
is effective, I would be inclined to put the blame there. It may be worth
trying an alternative KVM switch, or perhaps swapping the channels over.

FWIW - I've seen people report problems with Belkin and other relatively
more expensive KVM's. I have an el cheapo IOGear from Best Buy - never had
a problem and I've never seen any problem reports.

I had the same problem before (no-brand KVM). It appears that there
are some KVM without PS/2 emulation: they turn off the leaving port
instead of keeping it alive. Mine was this type before.

I solved the issue by buying an IOGear KVM. It is an excellent product
and never had a glitch since then. I fully recommand this product.

I don't know for sure, but I have a theory it is connected to the built in
cables on the iogear - some of the more expensive units come with
detachable cables.
