Subject: How to tweak 2.6.34 kernel for acer 5740 laptop ?

Dear Linux kernel Developers ,

My greetings to all of you.

I have compiled kernel a no. of times with the help of some online
tutorials, but this time I need some special information and hope you
kindly enlighten me. I have bought an acer 5740 laptop which equipped
with interl-i5, intel 3440 chipset, intel HD graphics. I tried to
install debian squeeze through net-intaller CD but the big problem was
ethernet which required tg3 driver. Hence I download debian's first two
DVD image and add those to insall kernel compilation tools. Now I have a
2.6.34 kernel compiled with tg3 driver and I get my internet back. So
far so good.

But I have still found some problems, I can't control the LCD brightness
and I have found from dmesg that

``````````````````
acer wmi: can't load, no such device
````````````````````

More over I have compiled the kernel with xframebuffer support and linux
logo ( both 16 bit and 32 bit ). But no logo is appearing during booting
and the *CLI screen is performing very very slow *. My old Desktop CLI
is performing very fast than this high end laptop linux CLI.

with the xserver-xorg ; if I use vesa as driver I can switch to
different virtual console by [ctrl] + [alt] + [F.. keys] ; but with
"intel" driver (xserver-xorg-video-intel), though I get the correct
resolution and color, it hang the box when I try to go to virtual
console. Hardware restart is only solution to get back the system.

I have a impression that I need to tweak the kernel to activate the
features rather than blaming the hardware. But I really don't know where
to look or where to activate the required options which in turn activate
these features. Could any one kindly put me on the right track ?

thanks for your time and please CC to me
