Thanks for testing! Some comments are below...

I will fix this. Once 2.6.39-rc1 is released I can make a patch fixing this.

Hmm, S_FREQUENCY apparently fails to check for valid frequency values.
Can you take a quick look at the code?

ENUMINPUT/G/S_INPUT are not allowed for radio devices. These ioctls are specific

I'll fix this as well. The drivers needs to be converted to the control
