Supporting every member of the Mac family, Aperture 1.5 runs on every desktop from Mac mini to iMac to Mac Pro and every notebook including both the MacBook and MacBook Pro. So you can run Aperture at home or in your studio. And you can take all your photos with you on location or to a clients office. Aperture and the Mac make one unstoppable team.
Sync to iPod: Take your photos with you by using iTunes to sync your entire Aperture library or just selected albums or Smart Albums to iPod
Pause, adjust volume, manually step backwards/forwards through slideshows using the Apple Remote that comes with most new Macs.
Browse and present slideshows even with images stored offline thanks to the new Automatically Generated Previews stored in the Aperture Library. Aperture lets you customize both the size and quality of the previews.

One of the following Macintosh computers:
Power Mac G5 with a 1.6-gigahertz (GHz) or faster PowerPC G5 processor
15- or 17-inch PowerBook G4 with a 1.25GHz or faster PowerPC G4 processor
iMac with 1.8GHz or faster PowerPC G5 or Intel Core Duo processor
Mac mini with Intel Core Solo or Duo processor
The iBook didn't ever ship with any of the compatible video cards and the screen does not provide enough workspace (1024x768).
I think the late model 12" with the 9550 should have enough horsepower to be able to run it if it is not locked out by Apple. It may work with a larger external display. I would expect some sort of hack to come out to allow it to be installed on unsupported hardware.
I wouldn't be surprised if Apple relaxes their requirements, based on them allowing MacBooks and Minis to be officially supported. Hopefully they let the user decide for the themselves whether or not Aperture is worth running on their hardware.
