Arnd,

oh, I didn't saw this randconfig error posting. NVEC isn't prepared for 
modularized builds yet (it's on the TODO list though). So better say SERIO=y 
here. Looking a bit closer, there is other stuff which can also be a module 
(GPIOLIB, I2C, ...) so these also need a =y.

Should a post a patch?
