Possible new ID 1f4d:b803

Greetings, I just recently acquired an USB tuner from the company "NPG" model "Real DVB-T F PLUS" (but the most common vendor/model with this ID is Lifeview LV5TDLX), looking for a suitable driver using the USB ID, I found multiple references pointing to use this driver. Trying the tarballs available from those sources, none of then could compile as I am using a "recent" kernel version (2.6.35). None of the Mercurial branches pointed in the wiki page detects the USB device as the ID is not listed in any of then. Here I paste the information dumped from the device just in case it can be added to the supported device list:

# lsusb
Bus 001 Device 002: ID 1f4d:b803

# lsusb -v -d 1f4d:b803

I have not melded with the IDs myself just in case I brick the stick, but if you thinks it is safe, I can replace the ids of one of the supported sticks and tell you about the results. Sources:

The circuit board is stamped HU394-T and has a Realtek RTL2832U chip on it.

Appears to be working for somone under the same source as above:
