I tried to run this on my Quad G5, but I never see suspend() or resume()
called. Do I have to do something to make autosuspend work?

echo "auto" > $(directry in sysfs for device)/power/level
And you'll see power events in syslog only if you compile with
CONFIG_USB_DEBUG

I only seem to see power/wakeup entries. I don't have power/level. Am I
missing some configuration option?

Probably CONFIG_USB_SUSPEND

that one is on of course. Do you think it makes a difference that it is
PowerPC system I am testing this with?

If it does make a difference, that's a bug. Runtime PM should work
anyway.

I really don't see any calls to suspend() and I am missing the
power/level option. This is the latest 2.6.27-rc3-git tree from Linus.

Odd. Send /proc/config.gz please.
