Yeah, demod chips are just like that. Then these are integrated like that:
RT2831U = USB-interface + RTL2830 DVB-T demod
RT2832U = USB-interface + RTL2832 DVB-T demod
RT2832P = USB-interface + RTL2832 DVB-T demod + TS interface

USB-interface used is pretty same for all these, thus it is split to own 
driver named dvb_usb_rtl28xxu.

SDR functionality is property of RTL2832 demodulator, but I decided to 
split it to own driver too.

Currently that SDR driver has support for devices having following RF 
tuners: e4000, r820t, fc0012 and fc0013. So if Hans has a device having 
some of those tuners, it should work.

Antti
