In the meantime I've switched to using mpd5 (/usr/ports/net/mpd5)
and /sbin/ipnat. So far, so good:

Incidentally the PPPoA section of the FreeBSD is very out of date:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/pppoa.html
The ambiguously named net/pppoa port in section 28.6.1 has been marked
as broken since 2009. (Ambiguous since it's only for a particular
brand of USB ASDL modem.)
In section 28.6.2 the example provided is a config file for mpd 4.x
which does not work in mpd 5.x.
net/mpd4 was deleted from the ports tree 11 months ago.
net/mpd5 doesn't seem to support PPPoA, only PPPoE. I could find no
reference to PPPoA in the manual or source code.
Not many people really need that these days.
PPPoA support is needed for obsolete USB modems which pass-through
ATM for the host to terminate. There are also some pci modems supported
by Linux, but I don't think they've been well supported on FreeBSD, if
at all.
These days there are better options that only require standards-based
support in the host. Most PPPoA-based ISPs also support PPPoE over ATM
- even if they don't advertise it or tell their low-level technical
support. Alternatively you can:
- use a NAT router that terminate PPPoA
- use a router/modem that bridges PPPoA to PPPoE
- use a router/modem that terminates PPPoA and passes the public IP
address to the host
