   Ok,

      What I have made now:

         1. Changed vendor id of PREP Pci bridge from 1011 to 1014 (ibm)
         2.  Tried booting and noticed that Bootloader did: 
pci_config_read: PCI Bridge address:10  value: 0xffffffff
         3. Found out that address 10 should have base adress in it.
         4. modified this with:

                        d->config[0x10] = 0x08
                        d->config[0x10] = 0x00
                        d->config[0x10] = 0x00
                        d->config[0x10] = 0xF0
               to be 0xF0000008

    Is this ok?(I just figured it out somehow)

       Now bootloader gives me:

        dma:command 0x24 not supported
        dma:command 0x25 not supported

   Just figuring out what these commands are....
