request_resource will fail, because the range is already taken by
sni_io_resource, while insert_region inserts the resource into 
sni_io_resource. The problem is that init_i8259 doesn't have the right
resource for doing the request_resource, if ioport_resource starting from
0x0000 is already taken by a PCI host bridge. I could probably write a
patch, which adds a parameter to init_i8259 for the resource, where the
request_resource is correct. No idea, whether this is worth the efford.

Opions ?
