Quoting the introduction: »In this post, I'll share how I ported the first version of Mac OS X, 10.0 Cheetah, to the Nintendo Wii. If you're not an operating systems expert or low-level engineer, you're in good company; this project was all about learning and navigating countless "unknown unknowns". Join me as we explore the Wii's hardware, bootloader development, kernel patching, and writing drivers - and give the PowerPC versions of Mac OS X a new life on the Nintendo Wii.«

The amazing part is that this guy went so far as to write new Mac OS X drivers (SD card, framebuffer, etc.) required to operate the Nintendo Wii.
Having managed to install and run OPENSTEP on a Frankenpad T61, albeit without network access, I'd wish someone similarily capable would create some network and PCMCIA drivers for the T6x Thinkpad generation to enable full use of its hardware capabilities.
