By erase I'm assuming you mean uninstall with RPM or something similar (rpm -e kernel-2.6.6-1.435 or whatever). Most people tend to keep a couple kernels around, just in case. You might start with rpm -qa | grep kernel to see what you have installed, then unsinstall one by one. I've always had to go in and update my grub.conf to remove the old kernel lines manually, and make sure my default kernel is set right. I'm sure others may have different experiences and opinions.
