There are distinct portability advantages but you shouldn't mix ioread32/iowrite32 with ioremap as that isn't guaranteed to work.
Hm, pci_iomap() boils down to ioremap(), so
readl/writel does fine and fixes up the driver.
Which brings up another issue with the latest patch: Anton, where do you call ioremap() or something alike to get the virtual address of the registers?
