Hi , Just wanted to share . I have an X61 Tablet as well Was tired of slow OSX and different issues with arch-i386 so decided to switch to x86_64 . I have installed 10.7.5 combo update after clean iatkos L2 install . Then I found on the internet everything needed to have my machine working . For sound I'm using a voodoohda.2.7.4 for keyboard and mouse I found replacement for ApplePS2 (I had to remove the trackpad plugin inside the kext to make the mouse work ) Wifi worked directly since I installed an atheros card and Ethernet worked with the Intel82566MM kext BAttery with voodooBattery.kext SDHC with VoodoSDHC.kext Let me tell you !! now its fast really fast . I was even surprised !!! Thanks for all your help the people behind those posts helped me a lot .
