[etherlab-users] bugfix for kernel 2.6.37 e1000 driver

[William Montgomery]

I had reported a kernel oops on this list a couple of months ago.  The 
oops occurs when starting the e1000 driver on kernel 2.6.37.  The 
following patch was based on a hint from Andreas Stewering-Bone and 
fixes the problem for me:
