I'm sure sales would be happy to confirm whether or not the platform as supported as part of the sales process.
The detailed certification information that used to be available on the Sybase web site is not currently externally accessible since SAP decommissioned the site - all that is currently available is the basic information in the SAP Product Availability Matrix (PAM) and the base release information available in the ASE documentation, which is still accessible at SyBooks Online
ASE support is looking into ways of restoring external access to the certification reports, possibly here as SCN documents or on the SCN wiki. I don't have any estimate for when this will be available, though.
