Well, i think you have not understood me fully. It is not just any old pci
slot. It is a dedicated 133MHz PCI-X bus. That is, the northbridge has two
such PCI-X buses, one is used to fake an AGP bus/slot, and thus reaches the
AGP 2x speed and specs, even thus it lakes the AGP extensions. It also can
only accept cards which are not AGP 4x or 8x only, since it onl supports 3.3V
mode. This means that from the radeons, the upto 9250 are supported, as well
as 9700/9800, but not the 9600/9550 ones. There are no 3D drivers above the
9250 ones anyway, so a 9250 with 256MB of ram like the one sapphire build is a
perfect match (an i think it is even fanless).
So, no, there could not be two such agp slots. Well, i guess there could be
any number of such slots, but they would share the same bandwith, as the
second PCI-X is shared between the 3 pci slots, the via southbridge, and and
the builtin firewire chip.

I would seriously doubt such, since like Michel said, powerpc linux is a
minority of a minority, and before we see games, we first need to see
proprietary drivers from ATI (rumored since over a year, but we saw nothing
yet), and nVidia (will never happen, unless it can sell them 100.000 boards a
month, or someone pays them for it).
