OK.  I removed the bcmwl proprietary driver.  I downloaded the 3 .deb 
files for amd64.  You provide no procedure for performing that download 
in any obvious way.  For example how am I supposed to obtain the proper 
names for a wget command or to download them by ftp to a specific 
directory.  In Firefox double clicking on each entry downloads it into 
the Downloads directory, not into the recommended separate directory.  
This is part of what I mean when I say your documentation is vague.  I 
installed, and booted.  The system now boots on kernel 3.18-rc6.  There 
is no observable change in behavior from kernel 3.16.  The system 
displays disk activity consistent with normal resume processing, but the 
back-light on my display is not turned on, so I have no choice but to 
manually reboot even though the system is completely operational in all 
other respects.  For example I can ssh, ftp, even http to the system.

Kernel 3.16 seems to have resolved all of the actual suspend/resume 
problems I had on previous releases.  But at least most of the time the 
earlier kernels and drivers would turn on the back-light when they felt 
like resuming at all.

I would stop bothering the kernel group and the X.org team if someone 
would just give me a manual command to turn on the damn light!  I can 
ssh into the system to issue the command.
