Hi,

I'm interested in this behavior.

hostapd ACS selects the ideal channel by survey data which wireless driver
given, so that
the final selected channel depends on the value that driver collected from
the chip.
I don't know enough about that ath5k is able to give a right
values(cycle_count ,busy_count,
or rx_count). Debug Log should be helpful for what you want to solve.

For example, what does the following command show?
$ hostapd -d hostapd.conf | grep ACS
