I use the 2.6.35 (maverick), on an Acer One netbook. Don't know if it really uses the intel_idle instead of acpi_idle, but its idle power usage is abysmal. Powertop reports lots of load balancing ticks (which is another bug that is supposed to be fixed in 2.6.35) and generally the laptop is burning hot.

I wish the linux kernel developers where a bit more concerned on power usage. It's killing the netbook experience (makes Microsoft's solutions much better, which shouldn't be the case)
