Actually, I suspect that you had an old daily image (which is based on 
*unstable*) that still used the 2.6.31-1 kernel while the udebs for that 
kernel no longer existed in unstable because they had been updated to 
2.6.31-2.

So, two options:
- either you really did have an incorrect preseed file
- or you had an outdated image

That setting mirror/udeb/suite to testing worked, was merely a coincidence 
and not a correct fix (because the only technically correct setting for a 
daily built image would have been sid or unstable).
