 Hello,
 
 That is ... strange.
 I used cardbus and PCMCIA cards in powerbooks, but those were either
 wifi or USB, so no memory ranges.
 Looks like that's supposed to be the memory space assigned to the
 bridge, which on my alubook at least, isn't in reg or
 assigned-addresses. Instead there's 'reserved-segment'. It's in
 'ranges' as well.
 Same on Pismo.
 I think I can see where that came from though, the 3400c has this:
 assigned-addresses      82009800 00000000 a0000000 00000000   ................
             0010:       10000000 82009810 00000000 80804000   ..............@.
             0020:       00000000 00001000 81009898 00000000   ................
             0030:       80801000 00000000 00000010 ........
             ............
 
 IIRC we BAT-map the entire PCI space anyway so this seems kinda pointless.
 
 have fun
 Michael
