Bzzt, here is the problem: you're not using the right package,
kernel-debug-debuginfo is for the kernel-debug package, a kernel built
with lots of CONFIG_DEBUG_ options turned on, please install the right
package, which is kernel-debuginfo-2.6.35.9-64.fc14.x86_64

Right, this matches what is in the kernel in the kernel-debug package.
Please install the right debuginfo package and try again
