If you subscribe to the Mandrake PPC Cooker mailing list, you can ask one of the MandrakeSoft developers about your problem. Since 8.2 is still a beta, I'm sure they would like to hear from you.
Subscribe to the Cooker-PPC mailing list by sending an email to sympa@linux-mandrake.com with the words "SUB cooker-ppc" (without the quotes) in the body of your message.
Good luck,
Phil
