I suppose I could, but that would basically negate any convenience of 
using the KVM switch.

I was a bit unclear.  The machine isn't actually asleep.  It's just 
thurned the monitor off.  The machine is still running.

I suppose I could rig up a script to send a mouse-command over the VNC 
port, but I'd like to avoid that, if possible.

Peace...  Sridhar
