I looked at PWM1 and PWM2 with an oscilloscope on test points CP174
and CP175, and played with them using sysfs. Period and duty cycle
look fine, so

I had hoped to test PWM0, PWM3, and PWM4, too, as they are all available
on test points, but I couldn't locate CP238, CP240, and CP241. The silk
screen for CP239 points underneath the heatsink, so probably all four
of them are obscured by the heatsink and/or switch board...
Gr{oetje,eeting}s,
