Come on, this is not a bug. These devices simply predate PCI 2.0 which
defined the well known class codes. Before this, there were only two
codes -- one for VGA devices and the other one for the rest.

One of such examples is the ancient i82378ZB PCI-ISA bridge which is
commonly used on Alpha systems. Fortunately, the concept of vendor and
device IDs existed since the beginning, so these devices may be easily
identified.
