I have a IBM Thinkpad and it's builtin mouse keys have the same problem. In my case, it's not the kernel support, as the problem is not present in gpm (console).
An external USB mouse behaves the same. Running: DISTRIB_ID=Ubuntu DISTRIB_RELEASE=8.04 DISTRIB_CODENAME=hardy DISTRIB_DESCRIPTION="Ubuntu hardy (development branch)" Alpha 4...
