I'm currently on Slackware 13.37 with standard kernel 2.6.37.6-smp.

I found that following keys don't work (tested with xev):
- Battery Status (Fn+F3)
- Screen Magnifier (Fn+Space)
- NumLock (Fn+Delete) works but produces no output in xev
And some keys, marked in commit as not enabled, works:
- KEY_SUSPEND (Fn+F4)

Also SysRq(Fn+Esc) and PrtSc(Fn+F6) produces same keycode.

P.S.: maybe you know about unofficial driver for SL laptops (currently not maintained by author). Is it possible to get some features from it (e.g. fan control) into asus-laptop driver?

Ok, for Fn+F3 and Fn+Space, could you try to apply the following patch, press them, and look at dmesg ?
(If you don't build your own kernel, apply the patch to acpi4asus-dkms, and use that module).

Sorry for bothering, but where is this patch?

I apply this patch to the kernel, then build and install it. Here is results (csv and ods): first column is a button(s), second - keycode reported by xev, third - corresponding code from dmesg after applying patch. Fn+F3 and Fn+Space produces no output in both. Some keys that produces output in xev also produces output in dmesg.

Hum this is very strange, keys that output in xev should not produce any event...

You're really getting "Unknown key 8 pressed" when pressing Fn+F8 ?
Can I take a look at your asus-laptop.c ?

Thanks,

Oh sorry, seems patch was applied not cleanly. After reviewing asus-laptop.c code and rebuilding kernel I think I get correct results:
Fn+F9 produces "Unknown key 9 pressed" in /var/log/messages and no output in xev
Fn+F12 produces "Unknown key 6d pressed" in /var/log/messages and no output in xev

All other keys produces no output in /var/log/messages and same output in xev as in previous attachment.
Also I found that Fn+Delete produces keycode 77 in xev only for first press. Second and other pressing gives no output, but seems it works.

Ok, so only Fn+F9 and Fn+F12 are producing messages ?
What do these keys represent ? (symbol on the key)

Yes, only Fn+F9 and Fn+F12 gives output in /var/log/messages

Fn+F9 used to work with external devices, mainly dock station. In guide this button described as "Eject ThinkPad PC from Dock".
Fn+F12 is hibernate (sleep mode)

Could you try this patch ? https://github.com/iksaif/platform-drivers-x86/commit/e282fb2e447c685204bc27518b84b0c1b1429f5b

With this patch Fn+F9 works fine, producing keycode 157 in xev. But Fn+F4 (standby mode) and Fn+F12 (hibernate) are produce same keycode 150.

Yes ... that's not great but Linux does not have a specific key for hibernate at the moment.
Feel free to edit the driver and replace KEY_SLEEP with any key found in /usr/include/linux/input.h .

Thanks for clarification and your work.
I'll try to lear more about kernel modules and maybe in future will try to adopt some code from unofficial lenovo-sl-laptop driver. Thanks again
