Yes, that problem sounds familiar - see my comment on this below, please.

I can't help in that case, since, up to my knowlegde, in favour to dvb-t radio there is no dab-radio in Austria.

Comment on the frontend loading issue:
This is my dmesg...
[30256.700149] usb 6-1: new full speed USB device using uhci_hcd and address 2

[30260.233362] DVB: registering new adapter (Siano Stellar Digital Receiver)
[30260.233828] DVB: registering adapter 0 frontend 0 (Siano Mobile Digital MDTV Receiver)...
Of course I am using the original ".inp"-Microcode, which I previously copied to /lib/firmware/`uname -r`/dvbt_bda_stellar_usb.inp
Since the autoload of the interface seems to have been forgotten within the source code itself, I created /etc/modprobe.d/siano.conf with the following line:
install smsusb /sbin/modprobe --ignore-install smsusb && /sbin/modprobe --ignore-install smsdvb
I hope this is the right way to do it and does not cause other problems.
I once repeat: the dvb-device is accessible, but the signal and snr levels stay at "0" permanently.
I remember, that a similar problem occurred in the siano-dev branch before. Mkrufky had a patch addressing this issue in former versions (adapted for 2.6.8-to 2.6.18), but it eventually did not find it's way into the repository.
Unfortunately, I do not possess a copy of the ancient patch file any longer.
