I now get:

est0: <Enhanced SpeedStep Frequency Control> on cpu0
est1: <Enhanced SpeedStep Frequency Control> on cpu1

I've enabled powerd too so I'll see if it does anything :-)

I get:

> sysctl -a dev.cpu | grep freq
dev.cpu.0.freq: 125
dev.cpu.0.freq_levels: 1667/31000 1458/27125 1333/22000 1166/19250
1000/13000 875/11375 750/9750 625/8125 500/6500 375/4875 250/3250 125/1625

There is also:
dev.est.0.freq_settings: 1667/31000 1333/22000 1000/13000
dev.est.1.freq_settings: 1667/31000 1333/22000 1000/13000

Although the dev.cpu0.freq was at 1667 earlier, so I dunno if powerd or
est has slowed it down or if it's just plain wrong! (This is while
plugged into AC.)

There are entries for dev.cpu.1, but no freq entries.

Unfortunately not. I set snd_ich_load="YES" in loader.conf, but when I
log into KDE, Arts just tells me that /dev/dsp doesn't exist.

I tried setting hw.snd.maxautovchans to 4, just in case, but no luck.
