I've bisected this to commit 571ff7584bb9e05fca0eb79752ae55a46faf3a98. It doesn't revert cleanly from RC2.
I think it's distinct from the other two reported suspend regressions. I'm not using acpi-cpufreq, and the issue doesn't affect resume.

commit 571ff7584bb9e05fca0eb79752ae55a46faf3a98 Author: Rafael J. Wysocki <rjw@sisk.pl> Date: Wed Jan 7 13:05:05 2009 +0100
PCI PM: Power-manage devices without drivers during suspend-resume
PCI devices without drivers can be put into low power states during suspend with the help of pci_prepare_to_sleep() and prevented from generating wake-up events during resume with the help of pci_enable_wake(). However, it's better not to put bridges into low power states during suspend, because that might result in entire bus segments being powered off.
