Okay, I installed the mainline kernel and can confirm I'm running it
after a reboot:
chorton@chorton-LIFEBOOK-T900:~$ uname -a
Linux chorton-LIFEBOOK-T900 3.11.8-031108-generic #201311122252 SMP Wed Nov 13
03:53:29 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
Unfortunately, after suspending and resuming, I still encounter the bug.

Title:
Stylus input stops working after resuming from suspend
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
I'm filing this bug here as per a suggestion on Ask Ubuntu:
http://askubuntu.com/questions/377047/which-package-should-i-file-a
-bug-against-for-pen-input
I have a Fujitsu LifeBook T900 which accepts touchscreen input via a
stylus which comes with the machine. It works fine until I suspend the
laptop, such as by closing the lid, then resuming, at which point it
immediately stops working.
A workaround is to restart the machine if this type of input is
desired and the machine was previously suspended since the last time
it was booted. Another workaround is to simply log out and back in.
Keyboard and touchpad (mouse) still work while the bug is active. This
is a fresh install of Ubuntu 13.10; the same machine previously ran
12.04 LTS and did not experience the problem there.
