The Prometheus pci busboard for A4000,is it ready for OS 4.0

I have read in the add of Redrumloa that it is, but on the OS 4.0 talkabouts I haven“t read anything yet about support for this ... can anybody help me out on this

I really am interested because a Mediator costs a lot more ... I only plan to mount a Voodoo4 card in it and an old networkcard (to start with) ...
