Thanks for you help, guys.
This is what I found on the apple web support site in the article about high speed media and super drives:
Computers that do not have a SuperDrive, or that have a SuperDrive from a vendor other than Pioneer do not need to be updated.
Here's the link.

I'm getting a sample G04 in the mail next week, so if it doesn't work, I'll make sure and post.
Otherwise, I'll be burning away.
Best,
