I'd like to use channel 157, as I've done in the past. I've read [1] that
157 is perfectly valid to use in the US. Apparently hostapd disagrees
with this assesment.

I'm using hostapd hostapd v2.0 [2] using the nl80211 driver on ath9k
hardware.

iw reg get: http://ix.io/5o7
iw list: http://ix.io/5o6
hostapd -dd /etc/hostapd/hostapd.conf: http://ix.io/5o8

I'm not quite understanding how hostapd came to the conclusion that I
can't use channel 157, and, more importantly, how I can fix this.
