If you want a kickstand but there isn't room for it where it would normally go, you can buy a rear-mounted kickstand that attaches at the very back of the frame
like in this photo. Just ask your local bike shop and they should be able to help you find one. I don't see why a slightly curved chainstay would be a problem.
I have a Sirrus also, and although mine doesn't have a kickstand, the bike shop told me that that's the only kind that would fit if I wanted to have one due to the clearance in front of the rear tire where a normal kickstand would go.
