Well, at least the core block device is there... which means figuring
out why uncompress isn't detecting that it should attach... Make sure
that GEOM_UNCOMPRESS is still in your kernel config file (you have a
g_uncompress.o in your kernel build directory), and maybe
#define'ing GEOM_UNCOMPRESS_DEBUG in geom/uncompress/g_uncompress.c
to get some debugging output...
