[CentOS] Centos 5.2 live cd won't boot

Hello All
Anyone have a workaround for booting the 5.2 LiveCD?
I'm getting this error:

    no root yet, udev rule will write symlink

Then I drop to a shell, with a message to create a symlink
to /dev/root and then exit the shell.  There is also a message
that it cannot find the root filesystem.

Is there a way to disable udev with grub?
Thanks
