Well, I've modified your driver to compile using 2.6.17 (one liner)
OK. What did you have to change?

Also the Makefile needed some tuning, but I think it's ok:

I'm not using udev, so I created the device myself. crw-r--r-- 1 root root 81, 0 Apr 17 2006 /dev/video
When I load the Virtual Video Driver, the device is created automatically, so that's not the problem.
I see the following dmesg output:

I don't get anything...
Are you sure you enabled the camera in the kernel config? The patch doesn't do it for you?
I'm not using defconfig, but:
CONFIG_VIDEO_DEV=m CONFIG_VIDEO_V4L1=y CONFIG_VIDEO_V4L1_COMPAT=y CONFIG_VIDEO_V4L2=y
CONFIG_VIDEO_OMAP_CAMERA=m # CONFIG_VIDEO_CAMERA_SENSOR_OV9640 is not set CONFIG_VIDEO_CAMERA_SENSOR_OV6650=y
