Subject: 2.6.25-rc6 hangs at resume after suspend to RAM on Mac mini Core
	Duo

Hi folks,

whereas I had working suspend with 2.6.25-rc5, I had a hang at resume
with git HEAD from March 19th (something after 2.6.25-rc6). I tried it
again and got another hang, so it seems to be reproducible.

Any hints what commit might have broke suspend? I won't have the time
to start a git bisect or any resume debugging using CONFIG_PM_TRACE_RTC
until next Tuesday.

This is a Mac mini Core Duo. Here is the lspci -nn output:
