Maybe at some point he'll "get" that the boundry issue is a pci bus-mastering 
spec issue and not a controller design flaw, as he seems to harp on this in 
just about every driver?

A more important question is "are these 32-bit cards, and if so, do they have 
enough internal buffer to do sustained 1GB transfers". Generally 32-bit PCI 
is too slow for GB, as it cant do sustained 1GB transfers. Some 32-bit GB 
cards are just a total waste.
