Log Message:
The 4.4.0 import changed the REGION_INIT() macro and uses with NullBox
(which is a NULL pointer) cause a memory fault.  The XalphaNetBSD and
XdecNetBSD servers fail with a memory fault on an alpha with a TGA
video adapter.  Change REGION_INIT() to REGION_NULL() where used with
NullBox.  Both servers will now run on an alpha with a tga card.  The
sfb code has the same usage.  Not tested on a TurboChannel box, but
inspection of the generated code shows the same problem would occur.
