[OpenBIOS] Sparc32 boots Linux...

The client interface is not used in Sparc32, only the last 32-bit machines 
with PCI/NC machines had the interface. Qemu implements much older, but much 
more common Sun4m type and there the older romvec calling system was used 
instead.

On Sparc64 situation will be different, client interface is the default.

Anyway, I found out how to do the calls, for example this works:
static int obp_nextnode(int node)
{
    int peer;

    PUSH(node);
    fword("peer");
    peer = POP();
    DPRINTF("obp_nextnode(%x) = %x\n", node, peer);

    return peer;
}
