OS: Ubuntu 11.10 Kernel: 2.6.37.6 Laptop: sony vaio vpc-z21x9r

The problem: I can't change level of screen backlight; also can't enable wi-fi. While using 3.0 kernel everything is ok, but the laptop discharges too quickly.

Results for lspci

02:00.0 Network controller: Intel Corporation Centrino Wireless-N + WiMAX 6150 (rev 5f)
VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

there is no wlan0 in ifconfig -a too. I've fount that kernel should already have drivers for this graphics controller, but when i load up in restore mode, it writes "fall" while trying to load up some video drivers.

To change the level of backlight i've alrady tried:

xbacklight -set XX

,

smartdimmer -s XX

and got this

init_ nvclock() failed!

also sudo setpci -s 00:02.0 F4.B=XX with no results. As for wi-fi, i've found driver but i don't understand how to install it. Here it is How can I fix these problems? Thank you for your help and time!

Also tried to fix problems with backlight writing GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_backlight=vendor

Still no results. Is there any sense in recompiling kernel, I mean 2.6.37.6. Can it make any improvements in the situation?
