This may not be at all relevant, but it reminds me of a case where I built my
own kernel for my TS-7200 and it only saw 8MB instead of 32MB. Eddie
immediately knew what the problem was... My memory is foggy, but I think when I
had built my cross compiler I had used too new a version of glibc, and this
affected the way the kernel interacted with redboot. Rather than downgrade my
compiler/kernel I think the fix was he sent me a new version of redboot which I
dd'ed
into place, and everything was fine. Perhaps you have some sort of similar
situation?
Good luck,
Joe
