OK.

I can do that?

<fx: typing, copying, fliddling...>

OK - Didn't know this - I have to edit drivers/Kconfig to have it 
included, but that looks intersting... If I could compile a module-less 
kernel that would use dahdi_dummy when no TDM400 card is fitted that would 
be nice...

OK.

Done that, thanks.

But for how many people... Of-course if I can built it as part of a kernel 
build then these don't get done as they're in the top-level Makefile...

Might be nice to know how many others do this sort if thing?

I guess the blackfin people do - ARM? I'm about to get a Nokia N900, and I 
know I can install gcc if it's not there already, but I somehow don't 
fancy compiling on the device itself, and I'm also looking at some other 
ARM boards too.

I think being able to run Asterisk on my next mobile phone is sort of neat 
- anyone ported it to Andriod yet?
