Subject: /proc/acpi/wakeup regression in 2.6.39-rc3

Hi,

with 2.6.38, I enabled wakeup from suspend to RAM with the USB keyboard
this way:

echo USB2 > /proc/acpi/wakeup

This does not work anymore with 2.6.39-rc3. Wakeup using the keyboard
won't work, and the USB2 line in /proc/acpi/wakeup doesn't change to
"enabled" after the echo command.

Is this intended? If yes, what is the new way to enable keyboard
wakeup?

Regards,
Tino
