KVM issues after kernel update

Hello,

Running RHEL4 on a Dell PowerEdge 2950, using a Belkin KVM connected
thru USB. Today I updated the kernel to 2.6.9-55.0.2.ELsmp from
2.6.9-5.ELsmp, and now once the monitor goes to sleep, I cannot wake
the system by moving mouse or using keyboard. Only way it will respond
is to unplug USB and plug back in - then it works fine until monitor
sleeps again. It worked fine before. Anyone else seen this or have any
ideas? Your input would be greatly appreciated.
