The driver list prints "(null)" for the NDIS driver when -h (help) or
an unknown switch is passed outputting the command usage. This is
because the NDIS driver is uninitialized when usage help is printed.
To resolve this we initialize the driver prior to the possibility of
printing the usage help message.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.
