I'd like to help you in the project but I'm no be able to compile the driver due to my kernel-2.6.26.8-57.fc8 source doesn't have the file v4l2-ioctl.h.
Could syntek-11xx source be included in a tree like uvcvideo tarball? http://linuxtv.org/hg/~pinchartl/uvcvideo/
So we can work using the same files and versions.
