That's a "hit-n-miss" approach at the easiest, and deep study at the hardest.
You will need to look at the tuner chip, I believe it is under the "can"
part of the WinTVGoPlus. If it just so happens to be a Philips TDA6503 chip,
you can use my patches as is. If not, you'll need to go to the manufacturer's
website for the chip and work out what to send it :-(

I rebuilt a kernel and rebooted. And rebooted, and rebooted :-(
