Really fast. If something gets in your way, turn" > On 2.0, the support is not built in. You can do it by figuring out the sizes of the partitions and fixing the disklabel yourself. The key is that the logical partitions are offset into the extended partition by, I believe, one sector. With this info, you can mount logical partitions. If you are not comfortable with playing with the disklabel, you may want to wait for 2.1. I am fairly sure it is supported in 2.1. On the otherhand, it is a fairly good way to learn. Make a backup of your disklabel, though.
