Shouldn't this kind of bugs be solved with quirks for hid? (in the
kernel - so evdev could also work - evtouch is not installed by default
and this device is handled by default with evdev).
See:

i have to ask the question again, is it posible to make the touchscreen
work in singletouch mode or not? i really really want to know.
on my search for a solution i found a script that allows me to move the pointer
all over the screen, but its slow and interferes with the left corner phenomen.

The 2.6.34 hid-mosart driver seems to fit better because it's a real
multitouch driver. This evtouch driver just uses the absolute HID
position information and doesn't provide multitouch therefore.
I don't see a relation between this bug and 549447, though. If I apply
the patch everything works.
