You know, I think I noticed something similar on my Dell Latitude D620, too.
I have some kind of Synaptics touchpad, which has a scroll area on the right. Up to Intrepid it just worked. In Intrepid, however, the scroll sometimes works and sometimes doesn't, despite a bit of tinkering. I _think_ it's dependent on suspending the laptop. I'll investigate a bit more and post some details.
