Fujitsu Siemens Amilo 2515 laptop Fn keys


Hello all!
I faced a problem on my new laptop (subj model). It has several Fn keys and they work partially:
1. Fn+F1 - Hibernate - works OK
2. Fn+F3 - Mute - OK
3. Fn+F4 - Display switch - NOT WORK
4. Fn+F5/F6 - Volume UP/DOWN - OK
5. Fn+F7/F8 - Brightness UP/DOWN - NOT WORK

I searched Internet and studied this problem on my laptop and get following results:
1. Brightness can be controlled through sysfs file /sys/class/backlight/acpi_video0/brightness
2. If I assign keys (for example UP/DOWN or any non Fn key) in HAL configuration (/usr/share/hal/....) - this keys starts to control brightness!
3. In BIOS mode and in Windows Vista (was preinstalled and later removed by me this keys WORK!
3. Fn+F4,Fn+F7 and Fn+F8 don't rise interrupts while Fn+F1,Fn+F3 and other working keys do. I check this by executing:

Code:
watch cat /proc/interrupts
and watching interrupt counters of i8042 keyboard controller

So I gess that something in kernel blocks part of my Fn keys. But I don't know where it can be. I have not found corresponding keyboard layout in Ubuntu so I don't know where to move now.
