This is my file for AMD64.
There are a couple of key notes. Always comment out:
#options ATA_STATIC_ID # Static device numbering
because it will screw up PC-BSD if you do not.
Do not remove drivers for hard drives. If you mess up on that area, you will be very sorry.
Always include the line
device miibus # MII bus support
under PCI ethernet nics. It is required by many other drivers.
My ethernet connections are rl0 and msk0. You will notice that these lines are not commented out in my example.
If you do have an older machine with an agp video card instead of pci, do not comment out
device agp # support several AGP chipsets
Most modern computers do not have agp video support.
One other note, every time you do an update with the csup supfile or cvsup supfile, it will overwrite the file
/usr/src/sys/amd64/conf/GENERIC
and
/usr/src/sys/i386/conf/GENERIC
save your working copy as
/usr/src/sys/amd64/conf/GENERIC.yourname
so you can go back to it for editing later.
If you are editing the i386 version of this file, you can comment out certain lines like
#cpu I486_CPU
#cpu I586_CPU
unless you bought your computer a garage sale for less than $1.50
When in doubt, exercise caution.

# latest information.
#
# An exhaustive list of options and more detailed explanations of the
# device lines is also present in the ../../conf/NOTES and NOTES files.
# If you are in doubt as to the purpose or necessity of a line, check first
