If you have the DVD iso downloaded:
1. put it at the top  level any drive except the / drive. {may only be 
required if you intend to format the / drive}
2. mkdir empty-folder
3. mount -o loop the-dvd.iso empty-folder
4. cp empty-folder/images/pxeboot/ vmlinuz and initrd.img to your 
existing /boot folder.
5. gedit /boot/grub/grub.boot
6. copy a boot stanza, but change the kernel and initrd lines to have 
the version-less vm.. and in..
7. reboot and press a key to get boot selection.
8. choose the new selection:
9. select Hard disk and choose the partition and folder where the iso is.
10. tell it you want to upgrade.

Whoolah - booting the installer from your own machine. This is 
definitely operational with an FC5 to FC6 upgrade on my machine.
