Did you try to build Wine using the FreeBSD port ?
If yes: Sorry, if you spent much time to debug this ...
I had added a patch to use LDT entries starting at 17
when some change to the BSDI emulation code was made,
that moved the highest LDT entry used by the system
from 5 to 16 (making the adjustment of the first free
LDT from 6 to 17 necessary, as you found out yourself).
Since -current got changed to no longer reject requests
to use LDT entries below 17 (even if the emulation code
does still depend on entry 16, but you won't need that
to run a FreeBSD Wine binary ...), I removed the patch
from the Wine port.
I now think that this was short-sighted, since it does
hurt compiling Wine on a 2.2 system, and since it means
that the Wine package will run on a -current system only,
too ...
But there were some requests to not put back the patch,
since the ports are always expected to apply to -current
before any other system.
I'm not yet sure what to do, but I guess I should put
back the patch at least until the packages have been
built for the 2.2 CD. Thereafter, the patch may be
deactivated again.
An alternative might be to merge the changed LDT entry
boundary check into 2.2. Since USER_LDT is off in the
GENERIC 2.2 kernel, this might be acceptable ...
I'm asking for advice !
