As far as I understand your problem is that each of the packages need
to be smaller than 1MB to get them transmitted to the SA1100. So why
don't you just split up the files and transmit it in parts? Something
like:
dd if=libc-2.1.2.tgz of=libc-part1 bs=1k count=500
dd if=libc-2.1.2.tgz of=libc-part2 bs=1k skip=500 count=500
Send each of the parts, reassemble them at the SA1100 board using cat:
cat libc-part1 libc-part2 > libc-2.1.2.tgz
Use md5sum to verify if the packages arrived in the correct order, and
you should be safe.
