I have multitouch screen overlays from PQ Labs that I would like to use with my Pi. They only have drivers for the x86 architecture.

Is there any way I can use these? If not, are there other multitouch overlays compatible with the Pi?

Can you edit your question and post some more specifics, such as the overlay manufacturer? Somebody here may have already got something similar working already, but without details... –  kolin Feb 6 '13 at 10:08

If the manufacturer provides open source linux drivers then they could be recompiled for the pi. There are a bunch of touchscreen drivers available for the raspbian kernel (src/drivers/input/touchscreen) some of which are apparently multitouch. The list is:

ADS7846/TSC2046/AD7873 and AD(S)7843 based touchscreens
AD7877 based touchscreens
Analog Devices AD7879-1/AD7889-1 touchscreen interface
Atmel mXT I2C Touchscreen
BU21013 based touch panel controllers
cy8ctmg110 touchscreen
Dynapro serial touchscreen
Hampshire serial touchscreen
EETI touchscreen panel support
Fujitsu serial touchscreen
Gunze AHL-51S touchscreen
Elo serial touchscreens
Wacom W8001 penabled serial touchscreen
MAX11801 based touchscreens
MELFAS MCS-5000 touchscreen
MicroTouch serial touchscreens
iNexio serial touchscreens
ICS MicroClock MK712 touchscreen
Penmount serial touchscreen
Touchright serial touchscreen

TSC2005 based touchscreens

Sitronix ST1232 touchscreen controllers

Obviously you then need userland software; Qt may have some support.
