You can press Enter at GRUB's boot prompt, and select the other kernel.

To make the default change permanent, edit /boot/grub/grub.conf, and change 
the default= setting. The first menu entry in Grub's boot menu is default=0, 
the second menu entry is default=1, and so on. Set default accordingly. Take 
care editing the grub.conf file, an accidental typo may have rather 
unfortunate results.

That shouldn't happen. Run 'rpm -e prelink', but this should really be 
investigated further. prelink shouldn't be hogging the CPU, like that. 
Before nuking prelink, wait for eat to start eating the CPU, find its pid, 
then do "ls /proc/$PID/fd". Wait a few seconds, and do it again. See if 
there are any changes. You might have a corrupted binary somewhere that 
prelink is choking on. Prelinking is good, you want to try to keep it 
around.
