Yeah, I'm 100% sure 32bit ram is outside ZII range. Otherwise you could never see 16MB, 32MB, etc...
When I had my A2000, I know I had 32MB 32bit on my PP&S 040 and 4MB 16bit ram on my GVP 4008 SCSI with GURU ROM. The 4MB on the board was utilized by the guru for DMA as ZII can't DMA into 32BIT ram.
Does the kipper board let you disable 4MB? I'm guessing, you'd run into trouble if you tried to add a ZII GFX board.
