I just fixed suspend/shutdown for e100 in 2.6.19, not sure why the problem still 
shows up. Since it's a driver/net issue, you should CC netdev on it tho, 
otherwise it might go unnoticed.

I'll open up the can-o-worms on this issue and see what's up with it.

I'm not so sure that this patch is OK, and I wonder why it stopped working, 
because I spent quite some time fixing it only a few months ago. Did swsup 
change again? sigh...
