lenny and raid 1 with adaptec 1220 SATA


I have a 2 1TB SATA hardisk configuration with an Adaptec 1220SA controller. I created a healthy RAID 1 array and now I want to install a lenny distribution on it. Now my first question is, in the debian installer I see two drives /sda and /sdb instead of only one. Now how to partition these disks?

I am aware that this controller only supports "hostraid" that is some kind of software raid. Can anybody give me some hints how to get this raid array under debian to work?
