I wonder (as the kernel is 3.8MB) if when booted it passes a 4MB limit.

Could you try the latest bootloader?  I did some work on it recently,
and it might have fixed this issue.  Note that a 4.x kernel should work
with it.

Nope 4 binaries won't run on 3.1 (as they expect netbsd 4 libraries)

Binaries would be the best option, even on a cats (with 233Mhz SA) I
don't build too much stuff.
