I gave the whole series a spin on Apalis T30 2GB V1.1A featuring a
STMPE811 and the EDT VGA touch panel connected to it still works
perfectly running LXDE on top of the modesetting X driver.
Unfortunately the 4.6.0-rc4-next-20160420 I used for testing is broken
beyond easy quick repair on i.MX 6 so I was unable to validate it on
there, sorry.
