Both gnome and KDE have had centralized password management as a standard feature for some time. I don't know whether they predate or postdate the OSX implementation; but they are there.

I'd be willing to wager they 'postdate' Keychain, as it came with "System 8.6" in 1999. And the functionality existed in many functions of the OS in the form of PowerTalk (shared printers, network shares, e-mail, etc) starting in the early 90s before it was split off and made directly available to 3rd Party applications.
Incidentally, Keychain has been Free (as in beer) and Open Source (as in APSL) for 'some time' now. It would be cool to see the various Unix-y distros pick it up too. Though the implementation might be a little crufty, having descended from an in house Apple project from the early 90s.
