When you compiled the stripped kernel under 1.5, was the system running a
GENERIC 1.5 kernel?  It could be that the the GENERIC 1.5 kernel used up
more RAM than the the GENERIC 1.4.3 kernel.

Barring that, I'd say there might be differences between the versions of
GCC bundled with 1.4.3 vs 1.5, or maybe it's in the compile options (i.e.
-O vs -O2?)  I've not actually looked.  I'm only speculating.
