The floppies aren't up against their limits.  The deal is that on i386 we 
stick the entire mfsroot on the first floppy to minimize the number of 
floppies needed (currently 3).  We can always split the mfsroot up like we do 
the kernel but that requires at least one additional floppy.  Also, Maxim 
seems to be saying that bzip2fs is worthless on i386 anyway due to the memory 
overhead (install media use a stock loader with forth, etc.) so I'm not sure 
bzip2fs on the i386 loader is even worth it.
