Thanks, that got me a lot farther.
I built and installed crda, did an iw set reg US, and then I was able to get past that error.
I then ran into an error about DTIM, but I found this patch:
http://hostap.epitest.fi/gitweb/gitweb.cgi?p=hostap-06.git;a=commitdiff;h=8fac32f5efa7a7c3fc6eee8d3723a09e7abe27fa
which got me past that.
So now hostapd is running without any errors. However, I do not see it as an access point when I look from a 5GHz N-Capable device (MacBook Pro or iPad).
Do you see any other issues in my configuration which might explain this?
(Also, am I correct that hw_mode=a should set me to 5GHz-only mode?)
