Are you running 5.1-release or 5.1-current?

I ask because I have used ULE on two different kernels so far on this 
box. One was 5.1-release running gnome2, mozilla, xmms. On this the 
mouse stutters really badly whenever anything is being compiled.

However on the 5.1-current kernel this behavior no longer happens and 
the mouse is fine.

I suspect ULE has had a few enhancements between the release and now.
