Fedora 9 PPC DVD wont boot

[Ian Chapman <packages amiga-hardware com>]

Hi All,

Has anyone successfully booted the install DVD or install CDs on a 
Powermac G4 laptop? No matter what I do, the mac insists they are not 
bootable. I had no such issues with earlier versions of Fedora on the 
same machine. I've tried the DVDs, the CDs, using the boot.iso all with 
the same effect. The sha1sums match the ISOs and they were burnt with 
k3b on a PC. The same mac is quite happy booting from say the MacOS X 
installation DVD. Any ideas??
