lsmod shows no yeeloong_laptop module loaded.

# modprobe yeeloong_laptop
FATAL: Module yeeloong_laptop not found.

This directory exists.

Directory 
/sys/bus/platform/drivers/yeeloong-laptop/yeeloong-laptop/input:input3/ 
does not exist. The only input* subdirectory there is input:input0.

I forgot to test the other function keys, so I was playing around with 
them just now. When I tried Fn+F1 the laptop went to sleep. When I 
pressed Enter it woke up again and, surprisingly, the wifi LED came on. 
I pulled out the network cable and Networkmanager connect to my wifi 
network. Pressing Fn+F5 does not turn wifi off again. I no longer get 
the rtl8187_open messages in dmesg after wake up. The only effect that 
pressing Fn+F5 has is that (in a terminal window) it either prints "%" 
(1 percentage sign) or prints nothing but has an effect on the key 
pressed after it (without Fn): with the arrow keys it's "[A", "[B", 
"[C", "[D"; with other keys it just blocks the key's input (prints nothing).

Example sequence and output from terminal to clarify (keypresses between 
brackets):

$
(Fn+F5)
$ %
(Backspace)
$
(Fn+F5)
$
(Arrow Up)
$ [A
(Backspace)(Backspace)
$
(Fn+F5)
$ %
(Backspace)
(Fn+F5)
$
(Arrow Down)
$ [B
(Backspace)(Backspace)
(Fn+F5)
$ %
(Backspace)
(Fn+F5)
$
(h)
$
(Fn+F5)
$ %
(Backspace)
(Fn+F5)
$
(Enter)
$     <-- No newline
(Enter)
$     <-- This is still the first line
$     <-- Only now I get a new line

I rebooted into the same kernel with the network cable unplugged, but 
again wifi only starts working after Fn+F1 and wake up. At one point, 
wifi disconnected and LED went off when I unplugged the power cable, but 
I couldn't reproduce that.

With this kernel I also have 2 battery meter applets, like I did with 
2.6.30.9. Fn+Arrow Up/Down changes backlight, as it has always done. 
Fn+Arrow Left/Right doesn't change audio volume (that didn't work on 
previous kernels either). The backlight level is now remembered between 
reboots and it auto-dims after a short idle period.
