AFAIK,in centos or fedora a boot partition cannot reside in an LVM 
volume.a boot partition must be a regular ext2 or ext3 file system.

or are you trying to boot from from wrong partition ? /dev/hda2 is 
labled as boot and is an ext3 filesystem. so i am inclined to believe 
that is the partition where the vmlinuz and initrd file resides. you 
need to change the line "root (hd0,2)" to "root (hd0,1)" during booting.
