Further info on this problem:

I came across this post:

   http://fak3r.com/2007/06/22/failed-to-set-xfermode-solved/

Regarding the same/similar problem on Ubuntu and a solution for it.  I 
have tried this solution with no luck.  I added "irqpoll" as instructed 
in grub.conf:


title Fedora (2.6.22.1-41.fc7)
   root (hd0,0)
   kernel /vmlinuz-2.6.22.1-41.fc7 ro root=LABEL=/ rhgb quiet irqpoll
   initrd /initrd-2.6.22.1-41.fc7.img


But no luck.  I still get the same error on boot and the DVD drive is 
not accessible.

Regards,
Langdon
