acer-wmi: rfkill and bluetooth enabling doesn't work as in 2.6.37

Hi all,

This is about Acer WMI driver and bluetooth support. I hope I'm at the right 
place with my question :-)

I tried to use bluetooth again on my Acer TravelMate 5730G and discovered a 
usability problem. I've checked 2.6.38-rc7:

0. On startup, the bluetooth LED is off, acer-bluetooth SW rfkill is blocked.
1. I have to enable the HW bluetooth switch to get the bluetooth LED running 
(USB device appears in lsusb). The acer-bluetooth SW rfkill is unblocked, the 
SW rfkill of hci0 is blocked.
2. Next I have to unblock SW rfkill on hci0 by a call to `rfkill unblock 
<number of hci0>`.
3. Last I have to enable the HCI by the call to `hciconfig hci0 up`.

How is this supposed to work? I tried to use "rfkill.default_state=1" on 
kernel command line, but without any success.

When I boot into 2.6.37, the bluetooth LED goes ON automatically and hciconfig 
shows the hci0 as UP.

Thanks.

Best regards,
Oldřich.
