[linux-dvb] semi-recent regressions in automatic loading of DVB modules

hmm, ok.  that's where the twisty maze of
symbol_request/try_then_request_module/request_module happens & i'm not sure
i follow the logic.

from what i can tell, dvb_attach just calls symbol_request which calls
try_then_request_module which in turn calls request_module which forces a
modprobe.

but - as far as i can tell, modprobe will be called to install mt352_attach
- which obviously isn't the same thing as mt352.
maybe this is an area where the age of my module-init-tools is showing. (see
below).

sure.
<http://www.interlink.com.au/ltd/ltd_dvb_tree_and_linux-2.6.18-rc5.tar.bz2>

fairly large (98MB) as i didn't do 'make clean' so all object files are
there also.  unpack it into a subdir as i packed my kernel + dvb trees
relative from /usr/src/
(tar cvjf ./ltd_dvb_tree_and_linux-2.6.18-rc5.tar.bz2 ./linux-2.6.18-rc5/
dvb-tree/latest/).  give it at least another 15 minutes to finish uploading
there.

yep!  (have to run this kernel or the machine doesn't boot :) ).
