Kernel 2.6 e power management

[ethanol]

Qualcuno è riuscito a configurare il kernel 2.6 per far funzionare il risparmio energetico come si deve? L'ho compilato con ACPI e performance manager, ma all'avvio mi ritrovo l'errore in ultima riga:

...ah, si tratta del 2.6.0-test9

Ho letto in giro che se hai problemi con ACPI puoi provare ad usare APM
