Net booting current snapshot on openrd and sheevaplug

[Jeff Penn]

Configuring the kernels for the openrd and sheevaplug with a root path,
e.g.:

make buildkernel TARGET_ARCH=arm KERNCONF=DB-88F6XXX
ROOTDEVNAME=\"nfs:192.168.0.10:/mnt/ST340014A/diskless/arm-8-le/\"

does not fix the diskless boot problem; openrd:

Sending DHCP Request packet from interface mge0 (f0:ad:4e:00:61:58)
Received DHCP Ack packet on mge0 from 192.168.0.10 (accepted) (got root

The compile problems I had with the i386 was a lack of disk space.  I
have not yet started testing diskless booting since fixing this.
