I don't think so. It looks like you are attempting to port a PCI driver, and attempting to access the device's register. PCI device regions in memory and I/O space are made available to the kernel with pci_mapreg_map(), which gives you a bus_space_handle_t suitable for use with thi bus_space(9) API. This would be a sugar-coated equivalent of ioremap(). >From then on, bus_space_read_(N/8) will match ioreadN() calls.
