Latest Jessie kernel is 3.14-2-amd64 #1 SMP Debian 3.14.13-2 (2014-07-24) x86_64 GNU/Linux.
This kernel does not recognize additional monitors because too old for this card:

However it does compile OK broadcom-sta-dkms so my wireless can work:

Neither the Liquorix kernel nor the towo kernel compile broadcom, tried both, so I cannot use wireless with those kernels, and I cannot have additional monitors with the older kernel.
So I have to choose: wireless or monitors?
I am obliged to choose wireless, so uninstalled both non-Debian kernels.
I already filed bug against broadcom, it has to be fixed because Debian 8 cannot ship with failed drivers on its kernel (3.16).
Siduction already has copy of failed build on their kernel, towo responded that broadcom driver is too old for advanced kernels.
Please find below copy of failed build for Liquorix:

You will probably have to grab the latest broadcom sta source here: www.broadcom.com/support/802.11/linux_sta.php

You should be able to install the driver directly from the source. Let us know if you run into trouble - I might be able to update the broadcom-sta-source package for it to build properly if you get stuck.

Thanks for answer.
Please create a .deb for arch amd64 for this package as I will probably run into trouble.
Also, I decided to plug a wire into this laptop and wait for problem to be solved in repo, as I said before I already filed bug against that package.
I need dual monitors more than I need wireless as this 17" laptop seldom goes out, if at all.
So it would be up to you, if you want to package that source I will be glad to test for you, dunno why the goddam maintainer doesn't do it.

Actually, this package looks like a lot of work. I just spent an hour figuring it out and pulling in the latest sources. I'll leave this to the maintainer to update.

Try pulling the latest source and doing a 'make' and 'make install'.

Thanks for trying, actually I don't want to stray far from repo because this is my main production system at present.
So I will have to patiently wait for maintainer, not that staying in repo is that much of a safeguard either.
