opensigma

Hello!
I have a PC compatible set top box with EN8471 chip on board. After adding a bit more RAM I am able to run standard Linux distro (Fedora 10) on it. With kernel 2.6.29 I can build opensigma kernel modules. Loading sigma-test.ko gives the following report in dmesg:
...

The output of "lspci -vv " is:

Is it possible to add suport for it?
