How to remove non-Fedora kernels?

[Antonio Olivares]

Dear fellow Fedora users,

Is thare a way one can remove non Fedora kernels manually, i.e, remove 

/boot/vmlinux-2.?????

and 

/usr/src/linux-2.???
or 
/lib/modules/2.6.????/.....


I have compiled two kernels and none of them work as well as Fedora kernel, I can't compile modules against them.  

I have compiled 2.6.33.1 kernel from kernel.org, I get bootsplash but booting takes longer than Fedora 2.6.32-9 kernel :(,, it has bigger intramfs? see here:
