I think you misunderstood.  The 10MHz limit is listed as the minimum 
operating frequency (for all conditions) not a minimum programming 
frequency.  I'd expect most chips would work at least a little below that 
but more than a factor of 2 is probably wishful thinking.

There are other small ARMs that will work with lower frequency inputs (The 
AD parts come to mind).
