HEADSUP: Some older drivers removed from x86_64

[Sascha Wildner]

Hi,

I've removed some older network drivers from x86_64, see  
http://lists.dragonflybsd.org/pipermail/commits/2014-June/270169.html

The main consequence for x86_64 users is that if your config is derived  
 from X86_64_GENERIC, buildkernel may error with:

Warning: device "ed" is unknown

In that case, just remove the line from the configuration file.

Regards,
Sascha
