I believe that the 20090616 snapshot had the problem where the DVB 
compilation pieces were disabled.  Since the trouble below involved 
compiling those DVB pieces then of course that snapshot will have built 
successfully.

I just checked the change history, and sure enough the next snapshot 
(20090626) has the fix that enables DVB compilation for the standalone 
driver.  So this behavior is explained.  See here:

Yes, but dvb_frontend.h is a required header and it is a part of th 
enormal source tree.  If this header isn't in 
/lib/modules/2.6.27.41-170.2.117.fc10.x86_64/source then that source 
tree is incomplete and there's no way it is going to compile correctly.

In my test builds here, this missing header is supposed to be found as 
drivers/media/dvb/dvb-core/dvb_frontend.h within the source tree.  It 
needs to be there, full stop.

I can't explain what is happening when you try to build against that 
other "full tree".  Perhaps this distro is doing something strange with 
its kernel trees.

One thing you can try is just download a vanilla kernel tarball from 
kernel.org and build it directly.  Very likely that it will work fine on 
your system - I do this all the time in Debian.  In this case you will 
get a kernel source tree that can be used successfully to build other 
stuff out-of-tree.

   [...]

I'm sure the rest of this is all different aspects of the same problem, 
that being that your "source" tree used here is missing pieces from it.
