hi,
i have fedora 16 installed with kernel version 3.2, as part of kernel customization i wish to customize kernel version 2.6.35.14 with a dummy module to learn the process.I have recompiled kernel 2.6.35.14 on my system and logged into that specific kernel at boot menu.Now my actual doubt is while building the source tree rpm using command 'yumdownloader --source kernel' it downloads the kernel version 3.2 instead of 2.6.35.14.Please help me customize kernel version 2.6.35.14 in any other way if possible according to my present situation.

Why downgrade your kernel? Would be more interesting to tweak the lastest stable release.

Here some links that might help:

main reason for degrading is actually i am working on an academic project, which requires a kernel version 2.6.x. I have a core i7 laptop which is with fedora 16 installed onto it, it was said that fedora 14 wont work for my laptop.I was also said that we can have both 2.6 and 3.2 both kernels , so i recompiled a new kernel.I just now found out that in my boot menu it shows all the kernel versions which are available but when i select version 2.6.35.14 it says initializing ram disk and then shows a failure notice and automatically boots into 3.2 version.

Something is missing for sure in your config you will have to go through all the editing and find out what can't be missing in order to have the kernel working. Read as much as you can about kernel. The link i put above is a good start.
I would go with Debian it come with kernel 2.6.32. and it is a good distro to deal with that stuff. There is a laptop option installation if you pick expert install text mode.
There is plenty documentation about how to compile kernels in Debian.
