See this http://maemo.org/maemowiki/HowTo_KernelCompilation .
If you don't want to do it in scratchbox target see also this http://www.gossamer-threads.com/lists/maemo/developers/3436 .
On x86 debian it is a matter of installing just the kernel sources via dpkg -i file.deb. It puts archive of n770 kernel source to /usr/src/ and then you can continue like with any other linux kernel. On non-debian linux you can extract the deb via 'ar xv file.deb data.tar.gz' and 'tar xvf data.tar.gz' commands. Just don't forget to prepend arm cross compiler to the path before compiling the kernel. This one http://scratchbox.org/download/files/sbox-releases/0.9.8/tarball/scratchbox-toolchain-arm-gcc3.4.cs-glibc-0.9.8.5.tar.gz should do the trick (extracted to /). Just do a make n770_defconfig ; make menuconfig ; make. It should find the cross compiler (arm-linux-gcc) and do the right thing. Image is in arch/arm/boot/zImage and can be flashed directly with 'flasher -k zImage -f -R'
As for the changes - I only modified file drivers/video/omap/lcd_lph8923.c I don't have original now, see modified version here http://fanoush.webpark.cz/maemo/lcd_lph8923.c

Frantisek Nice work. Can you put a unified diff on your page or post it here (I realize it's a work in progress, but I'd like to see where it all applies) What is the process for patching and building the kernel .deb? Brad
