I'm on 2.6.39. The patch doesn't apply cleanly, but I've fixed it up
manually (http://peter.korsgaard.com/lumio-2.6.29.patch).

hid-multitouch does get loaded, and everything looks OK:

Evdev output is also different, but it doesn't seem to ever generate any
events when I touch the screen.

Before I had:

I: Bus=0003 Vendor=202e Product=0005 Version=0111

With event16 + event18 never generating any events, and event17 giving:

Now with hid-multitouch I have:

I: Bus=0003 Vendor=202e Product=0005 Version=0111

P: Phys=usb-0000:00:1d.0-1.1/input1

B: PROP=0
B: EV=b
B: KEY=400 0 0 0 0 0
B: ABS=60000000000003

And event17:

Input driver version is 1.0.1
Input device ID: bus 0x3 vendor 0x202e product 0x5 version 0x111

Testing ... (interrupt to exit)
Event: time 1305886175.641112, -------------- Report Sync ------------

And then nothing. Any idea about how to progress?
