If both /boot/loader_lua and /boot/loader_4th fail in the same way, you may
be in trouble. There's a sliver of a chance that /boot/loader_simp might
work, but if the other two both fail, it's something common between them
that's likely shared by /boot/loader_simp.

I'd install old /boot/loader and then try to bisect where things went wrong
from your last update. Thankfully, it looks like the last known good one
for you was in March, and all versions since then you can rebuild just
src/stand w/o doing a full world so it should be quick to trace down. There
are maybe 20,000 svn changes or so, which should zero in on the right one
in about 17 tries... It takes me about a minute to build, so with luck
you'll know in about an hour...
