IF one looks at this picture
http://home-3.tiscali.nl/%7Eamiga/AmigaONE250402/DSC00020.JPGNotice in this PPC based motherboard ; the south bridge chip (speculating) is VIA.
VIA based chipsets can be found in mainstream x86 motherboards such in MSI, Abit, Gigabtye, Tyran and 'etc'.
VIA will be happy to see another market being opened for them.
Just hope x86 VIA/SBlive/Gforce2 problems wouldn't translate to AmigaOS/PPC world. ;-)
