 What about when I make good on the threat of creating a sound card with
 1-bit samples at 25 MHz?

Then you have delta-sigma modulation, and your card will probably
output 16- or 24-bit samples at a reasonable rate :-) Aside from that, the rate could
certainly be represented by a double precision value, which can accurately represent any
32-bit integer.
