<pre>OK I lied. I did spend a few moments thinking about the issue a bit more.
The BIOS N values are power of two. So assuming that power of two values are
somehow better, perhaps we can adjust the calculated M/N values a bit.
Something like this perhaps:
new_n = min(roundup_pow_of_two(n), 1 << 23);
new_m = m * new_n / n;</pre>
