BOINC is available for a wide array of platforms, and a lot of platforms are supported by the projects. You are probably better off asking a project to support your platform than using Wine to translate Windows calls.
It should be possible to use a native BOINC and run a Windows executable with Wine if absolutely necessary.
Test results for BOINC are still welcome as they help developers with Wine.
