>Description:
The current mod_cgi prevents back-end systems (such as 
application servers) from handling OPTIONS requests. This
effectively prevents any back-end system (accessed via
cgi) from supporting WebDAV, because DAV clients use an 
OPTIONS request to determine DAV support by a given resource.

I've sent along a patch that allows cgis to handle OPTIONS.
The patch is tested and running on our internal servers.
If I can answer any questions or elaborate on the problem,
please get in touch w/me:
