Contacting kernel-power maintainer (Pali) is useless, he lost interest in adding new modules ( Some time ago I've asked him to include *working* module for usb->ethernet adaptor, and he refused, claiming that:
"having module comppiled externally for KP and working is one thing, but including it in KP the way autobuilder will accept it is lot of work, and he doesn't have time for it".

So, I suspect even less chances to get such exoting thing as dvb-t dongles module - unless you can code it into KP yourself, and send him ready-to-use patch).

BTW, to have even slight chance, you must use dongle that have modules for support in Linux - propertiary-only ones won't work, as they have closed-source software for windoze only.
