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…
