people are obviously not getting what I'm talking about

It's not about motorola caches or motorola cpu bursts.. If the pci chipset only supports dma, the only way to get data out of the ram of a pci gfxcard is to dma it into some local storage/register on the busboard from where the amiga can access it - these dma transfers may be of any size the manufacturer of the busboard decides, and has nothing to do with zorro bus width or anything else amiga-related..
