Optimize kernel for Xserve

No problem.

The Tigon3 support in the 0.7d kernel fails to recognize Apple's version
of this card in any way whatsoever.  The driver won't even load.

I wouldn't have said you ABSOLUTELY DO NEED Ben's kernel if I didn't mean it.

You can compile it as a module or built-in, whichever way you prefer.

The same.

alias eth0 sungem
alias eth1 tg3

Me neither, my background is the same as yours.  However, the "G4"
should have told you what's going on - surely you know the Xserve has
PowerPC G4 CPUs.

Oh, I see.  I'm so used to replacing the PCI IDs file right away on any
new installs (I still install RH62 on all x86ware) that I didn't even
come to think of this possibility.

Do this:

cd /usr/share
mv pci.ids pci.ids.original
wget http://pciids.sourceforge.net/pci.ids

Now run a lspci.

> Do I have to compile the benh-kernel before that works?

No, you just have to get the newest PCI IDs file.
