[debian] Install kernel 2.6.11.12 with acpi on Debian Sarge

Just installed a Debian Sarge testing on my HP ze4500 laptop.
After at least 6 times compiling kernel, it works now, finally. Now the fan is running at a reasonalbe speed, quiter than before. And the laptop is cool as well. Eventhough there are still some issues need to be figured out, such as in KDE control center--> Power Management-->ACPI config, the options are gray.
But check the /proc/acpi folder, the status are ok.

I mainly rely on two HOW-TOs:
1. http://www.tldp.org/HOWTO/ACPI-HOWTO/
It's can be found in http://acpi.sourceforge.net/ homepage.
2. http://www.falkotimme.com/howtos/debian_kernel2.6_compile/
This one help me a lot with compiling kernel. But at the last time, I use a slight different parameter to compile kernel which I found in a disscussion board.

Follow the procedure in the ACPI HOW-TO:
1.load the old config file and select new features for ACPI. Learn two lessons fro 3 times failures. One is unselecting the useless DRM driver modules. The other one is selecting the EXT3 file system as built in, not module. I use EXT3 for / (bootable). The second issue relate to another issue I will talk about later.
2.Compile use "make-kpkg" command. At first, I keep getting "kernel panic: not syncing: can not find root fs..." error. One online article recommand the solution I decribe above, choose EXT3 as built in. In the compiling kernel how to, he suggests that create a initrd.img file. I check the kernel config file, the CRAMS is enabled. So I tried to use "mkinitrd" to create ram img file. But I only success once. After that, mkinitrd can not generate img file. I don't know why. Finally, I use "make-kpkg --initrd --append-to-version=.cannon kernel_image modules_image " command to compile kernel, and then "dpkg -i ....". It works for me. It will create initrd.img file and install it to /boot.
