It was enabled.  However, the problem is not 128k.  The loader from 4.0
worked fine and it was this size:

-r-xr-xr-x  1 root  wheel  182680 Mar 20 16:36 /boot/loader.works

Here's a broken one:

-r-xr-xr-x  1 root  wheel  186648 May 11 11:48 /boot/loader.old

If we do a little hex work:

> printf "%x %x" 182680 186648
2c998 2d918

Thus, one possiblity for the upper limit on size may be:

> printf "%d" 0x2d000
184320
