how replace direct use of ide_hwifs 2.6.27 from FC10

Hallo,

im working on a Kernelmodul which drives the IDE-Flasher. This is a device to programm flashchips like bios. ctflasher.sf.net

Now i read not use ide_hwifs direvt anymore. ide_hwifs is not exported. Google is full of the Patch itself, but no solution.

How do i now find the io-addresses of the unused IDE-ports to check them.

greetings
Gernot

old, now not working anymore code was this:

    for (i = 0; i < MAX_HWIFS; ++i)
    {
        ide_hwif_t *iface = 0;

        iface = &ide_hwifs[i];

        if (iface->io_ports[IDE_DATA_OFFSET] != 0)
        {
            base = iface->io_ports[IDE_DATA_OFFSET];
            if (request_region(base, 8, MODULE_NAME)!=NULL) 
                     	    {
                if (check_hardware_ide(base))
                {
                    printk(KERN_DEBUG "%s: ide-flasher found at 0x%lx 
(%s from i
de kernel module).\n",
                    MODULE_NAME, base, iface->name);
                    return base;
                }
                release_region(base, 8);
            }
        }
    }
