[ltp] Losing trackpoint after suspend

[Phil]

Hi
I've got a T60 running Ubuntu 7.04 and everything worked pretty much out 
of the box.
At work it sits in a port expander, I shut the lid, wait for it to 
suspend and pull it to take home. Previously on wake-up (out of the 
dock) everything worked fine. However recently (possibly following an 
update, not sure) the trackpoint stops working after a suspend, but the 
touchpad continues working fine. When I suspend, put it back in the 
dock, and wake-up the trackpoint works again. The dock also has a usb 
keyboard and mouse plugged into it - both of these work fine.
Not sure where to even start looking to determine what's going on but 
it's really annoying me - I dislike the trackpad and really want the 
trackpoint to work again.
Any ideas?

Cheers
Phil
