Swsusp often fails on -mm kernels because sysdev_resume doesn't get called in the resume path. So things like ACPI IRQ links used by modular drivers don't get restored.
We can work around this by using "pci=routeirq", so all the IRQ setup gets done at boot-time, but that's an ugly hack, and I expect that we'll trip over other sysdevs that need to be resumed anyway.
I don't understand swsusp well enough to fix this. It's not enough to just call device_power_up() before device_resume(), because it relies on sysdev_suspend() having been called before the suspend image was created.
