install of x86_64 dont_panic was peachy on this macbook core duo, and has been for the last two weeks. I've had some problems with other distros about half a year ago, but as I understand the arch kernel runs the mactel patches, whereas it turns out recent developments in drivers really make configuration for the macbook a doddle.
wifi now works with the madwifi drivers, I can mount my os x home directory as my arch home directory using the hfsplus kernel module (which now has write support), I have a swap file rather than partition to get around the apple partitioning system, 3D graphics is running using the fglrx drivers, and the weird function keys also work using pommed (sort of).
Some things are still on my todo, like getting suspend working, but I've read good things so I'm not too worried.
I'm really very impressed, a big kudos to the arch devs, thank you very much (where can I send the beer?)
Are you talking about a Macbook Pro 3 here?
No he has ATI graphics which hould be 2nd generation
