I have multiple kernel versions installed from yum/apt with no trouble. 
After upgrading to 2.6.8, I too had the CD burning problem, so I went 
back to I also have 2.6.8 and 2.6.7-1.494.2.2 
installed. I have been using the Synaptic GUI for apt-get mostly, which 
adds kernel upgrades into the grub.conf so that there are many kernel 
choices when I see the grub menu at bootup. I like setting it up this 
way because I have other choices if one kernel doesn't work. I haven't 
upgraded a kernel with yum for a while, but I think I remember yum 
simply replaces the kernel entry in the grub.conf so that you only have 
1 kernel choice in the menu. This isn't a problem, and you can always 
add in your own kernel entires if you want.

To install an older kernel version, you could just go to the repo 
website of your choice and download the rpm version you want, or if you 
know the exact name of the rpm, you could do

yum install kernel#2.6.7-1.494.2.2

Good luck!
