Dell ST2220T Monitor responds to touch only on warm boot from windows

Bug description:
Dell ST2220T Monitors have been purchased. On first install, the
touchscreen worked pretty well. But it started to behave weird after
restarts. The behaviour is as follows:
On cold boot touch never works. But once going to Windows 7 and coming
back after a warm boot, the touch works perfectly. From now, it works
until there are no cold boots. Once cold boot happens into Ubuntu,
touch stops working. This behaviour has been consistent. I tried to
put usbhid.quirks with <vendorid> : <productid>: 0x40 as mentioned
here http://ubuntuforums.org/showthread.php?p=10287057#post10287057
but it did not work.
This is on Ubuntu Natty.
A patch from Red Hat bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=703118 seems to help the
issue significantly, but, a few touch features (such as "click") seem
to still need some work. The patch doesn't seem to be upstream yet in
the mainline kernel.
SRU Request:
Impact:
Customer currently has 150 of these monitors with plans to expand to 1,500
next year and 10,000 in the year after that. Getting these devices to
work with ubuntu will help out a lot with cost reduction for the customer.
Patch:
See bugzilla reference above.
Steps to reproduce:
1) Install 11.04 (In this case the system was dual-booted with Windows 7)
2) Without the patch, the touchscreen only seems to work if the machine is
warm-rebooted from Windows. The touch features don't work at all if the system
is cold-booted into Ubuntu.
3) With the patch, the touchscreen appears to work with cold boots and warm
reboots, but, 'click' features on the touchscreen still need to be applied.
TEST CASE:
Apply the patch to the kernel, then test the touchscreen after warm
reboots and cold boots to ensure that the touchscreen is fully
functional. Customer has agreed to assist with testing, etc.
Regression Potential:
Unknown at this time. Patch appears to be pretty trivial and isolated
so regression potential seems to be pretty low.
