Hello:
I think you are correct, in that version of CodeWarrior there was no support for KL05 in 32-pin package. To use this specific package you need to install the latest version of CodeWarrior, which is CW v10.6, or even CW v10.5 already supported it. Here is an image I took from a project in CW v10.5, and you can see the CPU type options:

Hope this helps!
