The IP stack would make that much difference?  Interesting.
I recompiled a stripped minimal kernel on both 1.5B1 and 1.3.2,
and same thing.  Also, the 1.3.2 kernel was 412k while the 1.5B1
was 650k.  Same config file.  Any thoughts as to what has balooned
in the code, even with a stripped config?  Maybe I ought to compare
the sizes of the binary objects and see if there is a pattern to
the bloat.  That might point to where things are happening.

I picked up another MVII, today, so I will have two machines to run this
up on and compare bits.

This really has my curiosity piqued.
