I recently installed CentOS 5.2 64-bit on a partition on a MacBook Pro 17 
inch.  It installed just fine, but wired Ethernet is not available.  lspci 
shows it as nVidia...unknown.

Is it possible to get wired Ethernet running on this laptop under CentOS 
without having to create a virtual machine installation of CentOS?

If so, what is the magic?
