Funny you ask because I tried this yesterday on a AU1100 system with the 2.6.24 kernel (from kernel.org). I'm afraid I must say the kernel crashes when I enable power management. The reason I want to use power management is because I need to send the CPU to sleep when the system shuts down. I hacked power.c and reset.c a bit so au_sleep() is called when the system is shut down. Perhaps someone can confirm the powermanagement can be made to work with some fixes (it didn't work with 2.6.21-rc4 either).
BTW, for anybody interested in Alchemy PM code, here's the interesting link: [ftp|http]://ftp.enneenne.com/pub/misc/au1100-patches/linux/. It contains a lot of unmerged PM patches by Rodolfo Giometti (and not only that) from around 2.6.17 time.
Anybody interested in reviewing these patches and polishing them to be applied to a recent kernel?
I am, at least to some extent. But I'm not sure I'll have enough time from now on. Should have started earlier...
