Fair enough.  I've been thinking about something like that, being able
to control where in the LAR the blob goes (as well as being able to control
where in memory it gets loaded to).

But seeing as though the bootblock is 1) very special, and 2) mandatory
for the LAR, I don't think there is any problem in calling it out specially,
especially since the position and the concept is a hard constant (for now).

Otherwise, the alternative is for the user to have to do the math, and know
that they should put the bootblock at size - 16k in the LAR.  That seems

Yes, but it further breaks the 'ar' / 'tar' / 'lar' similarity.
