I have similar problem on my notebook (Casio CASSIOPEIA FIVA
101, Cyrix MediaGX plus Cx5520 I/O Companion: the intr_fixup
code is not yet committed though :p).
The BIOS says the router is located at 000:00:0, which is
the GX built-in PCI bridge, not Cx5520.
Is this a popular bug? If so, the patch is nice to have by
default, I think.
