We don't have the required kernel infrastructure to make this work.

There are two problems.  1) Getting the application to execute code in 
32 bit mode.  2) managing the 16/32 bit windows segments.

#2 is the big problem.  We don't have the i386_set_ldt() infrastructure.  
We might be able to get #1 working by having the process do a far jump 
to the 32 bit code user segment selector in the GDT, but I haven't 
messed with this yet.  There are so many problems to deal with it isn't 
funny, eg: delivering signals in 64 bit sigframe format on a stack of a 
process that is currently executing in a 32 bit %cs segment.

The problem set could probably be reduced by running 32 bit binaries, 
but again, we can't do without the i386_set_ldt() infrastructure.  I 
was reminded about this again today while checking out a different 
problem...  I think its time to do something about this missing 
feature.
