Ok, so my problem is that I was trying to set legacy-2.4 rates with one call to iw,
and legacy-5 rates with another.  Any non-specified rates get set to full bit-rate,
so that is why it wasn't working.

You have to do something like:

iw dev sta1 set bitrates legacy-2.4 24 legacy-5 24

Probably any time supplicant sets the rates, even if not specifying
legacy, it is going to over-write your previously set legacy rates.

I think the kernel should just not make any changes if the user does
not specify that entry in the netlink message, but that is a problem
for another day.

Thanks,
Ben
