This thread explains how they overclock the ar7161 chip on the Buffalo ag300nh, same model as the g300nh, but a different frequency.
I'm not too keen on how to compile my own kernel, so can someone with a g300nh show me how?

Be advised that it is VERY easy to brick hardware like this.
Brick as in, you cannot even get in via Serial recovery.
It's not really worth it to overclock routers.

According to that thread, if it fails, the recovery tftp feature still works.
All I know is that with FIOS 75/35 service I can saturate the router if the download is coming from a torrent with many connections. Even disabling bwmon doesn't help much.
I did change the dnsmasq script to nice -n -15 as when the router was maxed out, pages didn't want to load, even though torrents were set to lowest qos dn and up priority! I figured that the cpu load of the router was lagging DNS lookups.

Ticket created. I tested it again just now, putting dnsmasq at a negative nice number fixes the problem when the router cpu is swamped!
