Both these licences are acceptable to the FSF, so I can't see any issue 
with it.

There's then the matter of how to achieve this. Here's my recommendation 
of how to modify the banner:

NB, notice the indentation I have applied to the exception text, and the 
altered copyright banner markers.

You should also add COPYING.LIB for LGPL v2 to the top of the UFFS package.

I haven't been following things, but there may be a source of naming 
confusion with another UFFS (Unified FFS). Something to think about.
