How to compile the kernel 7.0-CURRENT AMD64 ?

[fulan Peng]

Hi,
I just installed FreeBSD 7.0-CURRENT on a AMD Opteron.
I cd /sys/amd64/conf
I cp GENERIC,v newkernel
ls:
.cvsignore,v    DEFAULTS,v      GENERIC.hints,v Makefile,v      newkernel
Attic           GENERIC,v       MAC,v           NOTES,v
I have changed the ident from GENERIC to newkernel
Then /usr/sbin/config newkernel.
config: newkernel:1: syntax error
This is the newkernel file:

head    1.466;
