    The driver is still using

    #define SPEEDO_SIZE 0x1000

    well sortoff it uses the same size when ioremaping

                    ioaddr = pciaddr & ~3UL;
                    if (check_region(ioaddr, 32))
                            continue;
            } else if ((ioaddr = (long)ioremap(pciaddr & ~0xfUL, 0x1000)) == 0) {
                    printk(KERN_INFO "Failed to map PCI address %#lx.\n",

    why are we using such high number since BAR foot print is 48
