Do the Dell drivers have a repository, or are they just on the CD? I don't think it would matter as long as you match the versions Daryna/Gutsy. Maybe you could install Mint, and then use the drivers off the Ubuntu CD. Do a dual boot. That way if Mint doesn't work, you will be able to delete it, and keep Ubuntu. I also don't think there are any Dell drivers that Mint couldn't handle. Most of them should already be included. What type of drivers are they? Try a Mint live CD, and see if everything works properly.
