I should preface this by saying that I don't have the schematic of
the RAMKeeper to refer to, so this answer is a bit of inference.

You will not harm your board by trying a 9v supply.  The worst that
could happen is that it will not work.

It is likely that the 9.5v supply is regulated down to 5v in any case,
and 9v is only about 6% low, and so should work fine.
