This allows the bt848 grabber to be loaded in the boot loader or
after bootup without the need for a custom kernel

+# Makefile for the bktr Brooktree Bt848/Bt878 PCI video capture device
+# Using the new FreeBSD 4.x device driver API (newbus) the Bt848 driver
+# can be loaded dynamically both in the boot loader phase and once
+# the system has booted.
+# The driver can also be unloaded, recompiled and reloaded.
+#
+# Use kldload bktr   and kldunload bktr  to load/unload the driver
+#
+# Note - as the driver requires contiguous memory, loading the driver once
+# memory has filled or become fragmented may fail.
