Hello.

Are there any other platforms requires special DMA zone?

Erm, RBHMA4[24]00 have 8259 on the backplane... And the NEC boards with the Rockhopper backplane as well...

Having 8259 does not mean it uses ISA DMA.  IIRC FPCIB0 backplane does
not have real ISA slot, and no on-board device uses ISA DMA.

   No, it does have ISA slot (a single one)! :-D

Does Rockhopper backplace have ISA slot?

   No, that one doesn't. :-)
