http://kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.25-rc7 – Changelog (lot of changes)
Hibernation and suspend (aren’t the same?) still won’t works on my notebook. Broadcom cards works good without patching.
What else…cpufreq still doesn’t work on Intel Celeron M C640, i2c doesn’t work at Intel 82801H chipset (so lm_sensors doesn’t works too!)
I hope it will change in future versions…
As far as I know Hibernation and suspend are not the same [; The main difference is because Hibernation flushes all ram data to disk and cut out power supply, the suspend is halting processor operation, but power is still on. This is because ram data needs to be refreshing after certain amout of time. I suppose.
