by linux driver?!

hi,
here in italy, many dvb-h trials are springing all over..
i'm wondering if there's already a dvb-h compliant (at least supporting
4k) demodulator available on the market, and with a linux driver ready..
for example i know the dibcom family:
http://195.137.248.72/539_Dibcom/Website/site/eng_accueil_applicationsproducts_products_chipset.htm
in this table, i can see both dibcom dib7000-h dib7000-m are supposed to
be "dvb-h" compliant
i've just checked in linux-dvb CVS, and actually there's nothing about
these chips, but there is already the dibcom3000mc driver, so, maybe the
path is ready, but, if i can elaborate, the registry actually carries
just one bit for the transmission mode (switching from 2k - 8k)
============
#define __DIB3000MC_PRIV_H__
/*
* Demodulator parameters
* reg: 0 1 1 1 11 11 111
* | | | | | |
* | | | | | +-- alpha (000=0, 001=1, 010=2, 100=4)
* | | | | +----- constellation (00=QPSK, 01=16QAM, 10=64QAM)
* | | | +-------- guard (00=1/32, 01=1/16, 10=1/8, 11=1/4)
* | | +----------- transmission mode (0=2k, 1=8k)
* | |
* | +-------------- restart autosearch for parameters
* +---------------- restart the demodulator
* reg: 181 1 111 1
* | | |
* | | +- FEC applies for HP or LP (0=LP, 1=HP)
* | +---- FEC rate (001=1/2, 010=2/3, 011=3/4, 101=5/6,
111=7/8)
* +------- hierarchy on (0=no, 1=yes)
*/
=============
anyway, do you know if this dvb-h thing is going to run (soon or later)
on linux devices?
do you know of a ready available HW (PCMCIA/USB) external adapter for pc?
thank you for your attention.
