Note that I asked about booting from the KDE Live CD,
not the Fedora DVD.
The KDE Live CD does not seem to have an images directory.

As a matter of interest, which root=UUID=... do you choose?

If I boot from the isolinux/vmlinuz0 and isolinux/initrd0.img 
from the KDE Live CD ,
the machine boots into the system on the root= partition;
if I specify root=/dev/sda6 , which is the partition for an fc11 system,
the machine boots into fc11, though with an fc12 kernel.
If I specify root=/dev/sda3 , containing an fc10 system,
it boots into fc10, the system on that partition.
