Apparently not, so it probably has to be added as a method of the pci node so it can $call-parent it and implemented in C instead of the forth hack I've tried to add. (SLOF also seems to call back to rtas for this.) So I'll try that and see what happens.
And yes, with config-b[!@] implemented as methods in C callbacks it finally starts poking the card regs. But it still ends in an exception, maybe it also needs map-out or some other words. I'm tweaking it a bit more then send the patch for commenting.
