I also got this type of probles once before. pls check initrd image.
pls performe below steps.

 gunzip -cd /boot/initrd-2.6.18-8.1.8.el5.img |cpio -t |more and see

then, check your newly installed kernel. as below

 gunzip -cd /boot/initrd-2.6.18-53.1.13.el5.img |cpio -t |more and see

pls check what is missing. If found, All you have to make an initrd by
using mkinitrd command.
