With a lot of shadow modules and dumps of the package table, I tracked
the issue down to before (modules look fine) and after (the nesting) our
middleware initialization call. I made an educated guess and added
_control87( _PC_53, MCW_PC ); immediately after that, and the game
is up and running. :P

So, this being DX9, I imagine the lack of D3DCREATE_FPU_PRESERVE
reared its ugly head once LJ2 was already active. I'll see if I can attend to
that properly and will report back if my assumptions don't hold. If they do,
that's probably worth putting a big warning somewhere. :)
