[linux-dvb] some questions on cx23885/xc3028

Hi,

I have bought a tv/dvb-t card which is unsupported at this time, this
is a leadtek winfast PxDVR 3200 H.
Product summary (as far as i can tell): cx23885 bridge, cx23417 encoder,
xc3028 tuner, zl10353 demod.

I have looked around the v4l-dvb tree, and finally got some results
today (ok, actually, I have just copied the parts I suspected to match
the card, I don't *really* now what I am doing).

So I have some questions:

Shouldn't the tuner (0xc2) be shown by the i2c scan?
I've tried w_scan, unsucceffuly :
w_scan version 20070909
Info: using DVB adapter auto detection.
   Found DVB-T frontend. Using adapter /dev/dvb/adapter0/frontend0
-_-_-_-_ Getting frontend capabilities-_-_-_-_
frontend Zarlink ZL10353 DVB-T supports
INVERSION_AUTO
QAM_AUTO
TRANSMISSION_MODE_AUTO
GUARD_INTERVAL_AUTO
HIERARCHY_AUTO
FEC_AUTO

the frontend seems to be correctly recognized (no?) but a full scan show nothing.
In the dmesg output there is nothing about firmware loading, doesn't xc3028 need one?
About firmware, I have two *.rom files which I got from windows install:  wf23885C.rom and wf416enc.rom, 
maybe xc2028 one is in this first, how to extract/use it?
Last question: how can I know what to use portb or portc? 

The following is dmesg output after modprobe cx23885 and tveeprom:
