Cool - in CVS now. I replaced the dvb_delay() calls with msleep()s since 
dvb_functions.h is gone now.

Interesting... I wonder what the models 90500 and 90501 are.

One niggle - according to the datasheet, the DTT7592 has VHFIII+UHF range, and 
the DTT7595 only has UHF range. Yet in the code, the min_freq of DTT7592 is 
474000000, and that of DTT7595 is 177000000.
