But you don't give me the option of _not_ setting it.  The dvbsky driver sets
it to 0x35 in its init_tab[] - as does yours - and then leaves it alone.

Whilst that may be so, something clears it between one call to
m88ds3103_set_frontend() and the next, so you probably need to unconditionally
reload the program init table.

I've made my version of your driver now set up the demod regs as per the
dvbsky driver for:

	S 11919000 V 27500000 3/4

but:

	./scan-s2/scan-s2 -a1 ./e.1 >/tmp/s -O S9.0E -D S2

still doesn't work for your driver, despite two goes at tuning.  I guess I
need to check the tuner writes too.
