First of all thank you all very much for all the info.
I managed to install SL on my P5K-E Wifi/AP, all devices are working as they should (including network, sound, graphics, etc).

However, I have a very big problem. Maya is not working -- the flexlm system can not get the system id -- the ethernet (MAC) address of the network card. I tried everything but I just could not solve the problem. It seems that the ethernet card is not considered as Built-in and so the flexlm doesn't take into consideration. I tried installing Chameleon 2.0RC2 and specifying the EthernetBuiltIn flag to yes, I forced the kernel to both 32bit and 64bit, I tried to put other IONetworkFamility kexts but I had no luck whatsoever.

Please help me to solve this problem as I really really to be able to use Maya.

Thanks

P.S. if I do a sudo -s in the Terminal the system complains about the UUID missing (installing PlatformUUID.kext fixes this, but the Maya problem remains)
