Thinkpad X20: How to wake up from sleep?

Thinkpad X20: How to wake up from sleep?

[Nguyen The Toan]

Hi,

I have a Thinkpad X20 and I'm using 2.6.0-test8. After issuing 
	echo 3 > /proc/acpi/sleep
the laptop seems to go into sleep properly. However, I cannot wakeup using any 
key (Fn, power, Fn+F4, Fn+F3...). I notices that when I use apm, the kernel 
says:

IBM machine detected. Enabling interrupts during APM calls.

Does anybody know if there's a way to enable keyboard interrupts during sleep 
in ACPI? 

Thanks,
Toan

PS: below is the output of dmesg:
