Mr Dominik, all,

	I tried your patch on top of the kernel that came with ubuntu
edgy (and had sufficient trouble with it, I do not know if I'll be able
to try with a recent kernel.). This message is in copy to akpm which
asked me a report on the same problem.

I applied your patch and this one: 

but the kernel continues to ignore the second function of my card.
Moreover, now the modem does not work even with the dear old cardmgr:

Mr Morton, do you still think I should open a bug in bugzilla? Even if I
have not tested a newer kernel? It seems to me that nothing has changed
over there, and this _is_ a regression (from 2.6.13, even).


PS: can anyone point me to a tutorial on howto install a new kernael
easily on ubuntu? The procedure they point to (creating deb package,
installing, etc) are quite cumbersome. Anyway, I will try.
