Smiler: Nothing of the sort. Intel don't make PCs (to my knowledge anyway) and they're _certainly_ not in the business of making "PCs" with ARM processors. They make development boards, so people can try out the XScale. Often these boards are PCI cards themselves, so usually there's no video at _all_.
The question about AGP on the Iyonix is already well answered on the Iyonix website. You should read that before making any more presumptions.
