You can now have the hibernate (suspend to disk) mode which is enabled on the latest PowerBook revisions. I have enabled this on my iBook 12" (1.33GHz, Radeon 9550) along with the screen spanning hack and it works fine. This feature is handy if you need to change batteries without shutting down your computer or you operate your iBook/PB without a battery inserted.

Have a read of the following on how to do this:

Also if you use the screen spanning hack with the clamshell mode on you iBook, you'll need to edit the script provided on the first link. Change 00000000 to 00000008 as described at:

As one of the articles says, Safe Sleep does not work on the 867Mhz 12" Powerbook.
