Thanks Bryan, I really appreciate that.  Actually, David
McKay also sent me his version, which was great.

I compiled his version (based on modutils 2.3.7) and had
the same problem.  I fixed it quite simply by adding
these lines to arch/sh/kernel/sh_ksyms.c:

#include <asm/pgtable.h>

EXPORT_SYMBOL(flush_dcache_page);

EXPORT_SYMBOL(memset);
EXPORT_SYMBOL(memcpy);

(I don't know if this is the way to really fix it - simply
does not imply correctly!)

I too compiled busybox this evening.  Wow, it's truly
impressive!

Yes I'm fairly sure it did.

Anyway, my thanks again to you and David.

Mitch.
