ipw2200 is really bad. ipw2200 by itself means the difference between whether the CPU spends it’s time in C4 or not. Though it seems the bug is not in the laptop but in the AP I’m connected to causing wakeups. Which really stinks since my router doesn’t give any obvious options to change it.
ide0 is waking up because of constant harrassment from hald. hal-disable-polling is included in v0.5.9. Which according to bug #176380 will be stablilized with Gnome 2.18.
ACPI is waking up due to queries from gkrellm2. Changing configs in gkrellm helped this.
