Yes,
I got an old iMac and booted with the Crux-2.0 PPC version. This is my first time installing linux on a Mac and the first time owning a Mac, haven't used macs at all.
The install went easy, just use the kernel they shipp on the CD, get the system up and running then do a compile later. That's what I did. My G3 333Mhz iMac and 96MB of RAM took a 1/2 hour to compile the 2.6.11 kernel.
Switched to udev and its fine. Loaded the binaries from the Evolution version and now have a Gnome 2.8 desktop, very nice. I'd hate to have to do compile on all those apps...
So the hard part for me was learning what HW is in this iMac. I did a lot of googling to get clues but going to board like this would have been the best place. Glad to see it up.
Anyway, i learned what sound and NIC driver to build mostly by trial and error. The same goes for the XORG config, that was hard. I get a lot of general tips from all around , some from debian some from gentoo.
Here's a couple that gave hints in some way or another....
