building Linux

[Chuck Robey]

I can't seem top get linux compatibiilty working.

I tried doing a kldload linux, it told me there wasn't any linux.ko.  I 
figured that I need a new kernel, so I just compiled one, but that 
didn't make me a linux.ko.  OK, I went into NOTES and searched for 
LINUX, found several, and some with made me wonder if there was a x86 
dependency (my system is a dual amd64).  What config options do I need 
for Linux compatibility?
