KB9202 booting large kernels

[David Sharp]

i have been succesful with smaller nfs-root kernels booting on the
KB9202.  however, when i try larger MD_ROOT kernels it does not work.  the
break point is around 2.6MB total kernel size.  as the size approaches 
that number there will be some error messages about elf linker not finding a
symbol, or no error and just garbage on the console.  after passing the 2.6M
mark by more than 10kB it silently hangs.

does anyone have an idea what might be going wrong?
