Hi!
As some people before I had the 'trackpoint does not work' problem
after upgrading to 2.5.XX:
That was:

the trackpoint of your dell won't work until:
- hibernate and wake up the system again
- plug in an external mouse (you may remove it immediately)

it seems that dells hardware is disabling the trackpoint if you
probed for the touchpad.
A device reset after probing does help, but I've no idea how this
would affect other synaptics touchpad devices although I think
most devices will not complain one extra reset.
