OK, so: If we link all the modules into the av7110 as is, it will consume 40k 
for the frontend drivers.

Before we start getting excited, is this actually a problem? The embedded 
platforms will only include one (or maybe two) demodulator drivers, which are 
individually quite small. Its only the av7110 that needs 5 demodulator 
drivers.

I'm going to remove the ifdef stuff I've added 'cos its horrible -  I had to 
add it to realise HOW horrible. The av7110 can be sorted by splitting it up 
into separate DVB-T, DVB-C, and DVB-S drivers. Any volunteers? If not, then 
it stays consuming 40k. Most people will be using far more than this because 
of our previous advice to "compile and load all frontends".

The demods themselves can obviously be optimised better as Holger says. 
However, my motivations in this are to fix the clashes, allow the demods to 
be customised better, and remove the card-specific code in them. If people 
want to then improve invididual demods for code size, speed, etc, please do!

I'd like to stablise what we have without making any further changes - its hit 
nearly 75% of the files already.
