Subject: how to migrate these drivers?

I want to fix these drivers so that they compile in 2.5. Is anybody
working on it? Any rule of the thumb to do it?

Thanks

Read Documentation/DMA-mapping.txt, especially "Types of DMA mappings",
then figure how it's used in drivers/net/{3c59x,epic100,eepro100}.c for
example.
Side note: pci_{map/alloc}_xxx must be balanced to avoid leak -> a straight
search/replace virt_to_xxx/pci_map won't necessarily be enough.
