Help setup. Would like to try Media100-HD

I am using a G5 dual 2.7 with AJA Kona 3x card and a Convergent Design LE box. Upgraded to an Xserve 3.0 Quad Core Xeon pre 2008. 10 gig ram. Its the last machine I can make use of the Kona 3 PCI-X card (according to AJA). Can anyone here help me in what software versions I need to be able to use Media 100-HD? Like Kona driver version, Mac OS and quicktime versions, Media 100 version and those small details to get me started.
I read somewhere that G5 wont be able to use ProRez that is why I moved to an Intel Mac.
Thank you
