The .jdk detection system used by Java Preferences does not use the $PATH set in your shell, but rather scans the */Library/Java/JavaVirtualMachines directories for JVM bundles to load.

The Mac OS X port has changes to the build system to create a parallel "1.7.0.jdk" product bundle. This bundle contains an Info.plist file and structure that is recognized by the Mac OS X Java detection/launching system. It would be perfectly plausible to re-bundle a PPC BSD-port product, and put it in ~/Library/Java/JavaVirtualMachines, but the work was simply never done for the BSD port.
