Earlier versions of 11.x also had the "SwedishChef" as the process name when launched by the tivoApplicationLauncher. I forget which version that began with. *edit* looks like it began with version 9.3, reference here: link
Try to cat /etc/build-version to see what version the filesystem reports. Then you can check /SwSystem and /State/ServiceConfig in MFS for other info about the software version that is running. I don't think tivoapp will report a version, but you can always run sha1 over it to get a checksum for it.
