Thanks to this guide, I finally managed to get the Airport Extreme card (Broadcom’s Wifi Controller for Apple) to work under Kubuntu. My 12″ PowerBook G4 is now set up to dual boot between Mac OS X 10.4 and Linux because I don’t intend to upgrade it in the future.
Despite speed, stability, compatibility and security, the latest version of Kubuntu/Ubuntu is still not fool-proof. I was impressed when it recognized my Bluetooth hardware, but when I came to change my display setting from, “custom 1″ to ’12” Apple PowerBook’, the GUI completely stopped working! I had to resort to writing commands to autodetect my display, and even after that I was stuck with 256 colors. Thankfully, there was a backup of the initial preference file and after a few attempts I was able to get it restored.
Overall, I think the Ubuntu development team is heading in the right direction, but in the meantime, I haven’t found any particular feature that I would want on OS X. Keeping in mind that the Linux is completely free, you can’t really complain :P
