Followup, I decided to 'cheat' to see what I could accomplish:

1) Outside of 'scratchbox', I modified the permissions on my 'tmp' 
directory:

[root at frodo6 dmenns]# chmod 777 /mnt/sda3/maemo/scratchbox/users/dmenns/tmp

This then allowed me (inside 'scratchbox', while signed on as a user, to 
create/modify files inside '/tmp')

2) I then ran into another problem:

mmap: permission denied (while trying to run 'python2.5')

I found this:

So, again, outside of 'scratchbox' I did this:

echo 4096 | sudo tee /proc/sys/vm/mmap_min_addr

This now lets me run 'python2.5'!  I don't know if this is the end of my 
problems, but I am getting further!
