Sleep Memory Extension "fixes" iBook/PowerBook wake-from-sleep bug (sort of)

Apple has released a Sleep Memory Extension for iBooks and FireWire PowerBooks. It is also listed on this special web page (thanks, Ernst Mulder and David Shaw). Apple states that the extension fixes a bug "which in very rare circumstances can prevent your computer from properly waking up from sleep." Although it does not say so, this is presumably the same bug that can lead to data corruption on your hard drive following this wake-from-sleep symptom (as covered previously here on MacFixIt). However, the extension is more of a work-around that a true fix. Apple explains: "After restarting your computer, the 'Preserve memory contents on sleep' checkbox will still appear in the Energy Saver control panel, but the checkbox will be dimmed and unavailable." In other words, it forces the disabling of the option known to precipitate the problem (as previously stated in TIL article #25130, now deleted). A true solution (that allows this option to be enabled) is still yet to come (we hope!).
