Yes, error handling in the low-level ARM communication functions
is pretty weak. But I added some checks to av7110_bootarm() so
we should catch the case where communications doesn't work

I'm not sure if the frontend problems are AMD64 related. Maybe the
frontend doesn't work with weak signals.

Could you try the patch I attached here?
http://linuxtv.org/mailinglists/linux-dvb/2004/02-2004/msg00250.html

Or alternatively, just set 'buf [3] = 0xc0;' in tsa5060_set_tv_freq()?
