I'm concerned more about hardware than software. Specifically, I am using a Microsoft Wireless Comfort Keyboard/mouse combo that I really like, using the Voodoo PS/2 kext from Multibeast 3.9.1, which is 32 bit only, to run Snow Leopard. When I try to change to a 64bit boot by deleting arch=i386 from org.chameleon.Boot.plist, the keyboard quits functioning.
I know, I know, I know. Get with the program and buy a bluetooth keyboard. It's what I did for my real Macs. And my wife doesn't know the difference. But all Mac bluetooth keyboards that I have ever seen just plain suck. Even the $150 Logitech is subpar. (IMHO, of course, but there you go....)
Anybody know how to get a PS/2 keyboard working in a 64bit environment?
