I'd like to add some notes here, just for reference.

After having installed the stuff do the following: (from diskless(7))

Still sitting in the source tree.
% cd etc
% setenv DESTDIR /some/nfs/export
% make distribution

This will populate some important files in the etc directory. W/o this 
step I ended with some magic lockups since my nfs directory could not be 
mounted (rw).

Then you'd need to modify your etc/fstab and your etc/rc.conf
Here are my samples:

[andreast@tc] /export/netboot/ppc64/etc/> cat fstab
# Device   	Mountpoint  FStype  Options    Dump    Pass#
server:/nfs-mount	/	nfs	rw	0	0

[andreast@tc] /export/netboot/ppc64/etc/> cat rc.conf
hostname="bohrium.andreas.nets"
ifconfig_gem0="DHCP"
nfs_client_enable="YES"
sshd_enable="YES"
ntpd_enable="YES"
keymap=swissgerman.macbook.acc
ntpdate_flags="europe.pool.ntp.org"
ntpdate_enable="YES"
rpcbind_enable="YES"
rpc_statd_enable="YES"

During a private mail exchange we found out that the current loader does 
not really work with netbooting. A patch is needed, I guess it will be 
applied soon on this branch. For the record, this is the ci on trunk:
http://svn.freebsd.org/viewvc/base?view=revision&revision=204129

And now some notes to my machine, it is a Dual G5, 1.8GHz.

SMP does not work yet.

Also, the network interface is not supported yet, the chip behind is a 
Broadcom 5421 or also known as 54K2. I need to find the right way to 
integrate the driver into the network framework.

I'd like to thank Nathan for this impressive work, it rocks!

Andreas
