Hi Pierre,

I'm also using power management on the at91sam9260.

I have also made that change in pm.c.  I've tested it with 2.6.20.4
and it seems to work.

Please post your mods to the list when you are finished.  I will
gladly help you test them.
Are you going to implement slow clock standby mode?

Michel
