Hello!
My description above was for a already compiled kernel from suse (in a rpm)
LVM has nothing to do with a bootloader like lilo or GRUB.
If you want to use the kernel from
www.kernel.org, you have to extract the kernel to /usr/src/(kernel).
In this directory launch the kernelconfig by "make menuconfig" (from console) or make xconfig (from GUI).
Choose your options and then save and exit.
type "make" in console and then "make install".
Afterwards you must add the new kernel to the bootloader.
Greetings
