Hi, I have here 3 Dell Vostro V13s on which I was able to reproduce the original problem, by suspending them and upon resume, the mouse pointer would not work.
My workaround was to rmmod psmouse and then modprobe psmouse, this reenables the mouse functionality. Of note, David Bensimon tried reproducing this problem on Lucid (10.04) with the 2.6.32 kernel and was unable to recreate this issue. However, I got hit by it under both Natty (2.6.38-11 from proposed and the original 2.6.38-8 kernel from Natty release) and Oneiric (3.0.0-7.9). I also have a Dell Latitude 13, it's almost 100% identical to the Vostros, and also reports a Synaptics touchpad, but this one seems unaffected by the problem, I can suspend/resume and the pad keeps working. David suspects the BIOS revision might also be a factor in whether the touchpad restores correctly or not. On my test systems the patched kernel (Linux version 2.6.38-11-generic (root@gomeisa) (gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu4) ) #49~lp810327v201108091824 SMP Tue Aug 9 17:25:25 UTC 2011) does NOT reenable the mouse after resuming. I'll attach dmesg from both Vostro V13s to see if any useful information comes up. Andy, these machines live for testing so if you need either me or David to run tests or provide hardware and/or debugging information, please don't hesitate to ask. We can install and test anything you need. Also, if a separate bug would be better for the Dell Vostros, let me know so I can file accordingly.
