Can you send me a diff against the current Benh kernel?
I just inserted these (useless) printk() to a non called function and
now it works so far for me.

find_pci_device_OFnode(unsigned char bus, unsigned char dev_fn)
{
/*      char blubber[60] = ""; */
        struct device_node* np;
        unsigned int *reg;
        int l;
/*      printk("I am just a dummy ...\n");  */
        for (np = allnodes; np != 0; np = np->allnext) {
                int in_macio = 0;
                struct device_node* parent = np->parent;
                while(parent) {
                        char *pname = (char *)get_property(parent, "name", &l);
        printk("I am just another dummy ...\n");
        printk("I am just another dummy ...\n");
                        if (pname && strcmp(pname, "mac-io") == 0) {
                                in_macio = 1;
                                break;
                        }

Bit ugly.
