Bug#298581: Apple's Shasta I/O Controller not known to kernel? [was Re: [Netboot] Ethernet Driver on 1.8GHz G5?]

[Francois <f.taiani@computer.org>]

Hi all,

I've looked up the PCI device code, and according to [1] and [2]
106b:0051 corresponds to the Shasta (Sun GEM) Ethernet Controller of
Apple [3].

I'm using the kernel/modules from Sven Luther [4]. Could this mean that
the current sungem driver does not recognise the Shasta controller?
