Yeah.  That's what makes the lspci approach unusable for my purposes.

The approach I want to take is this:

1. Get guaranteed access to the DMI data, either via a /{proc,sys}/dmi
   or /var/run/dmi initialized at boot time.
2. Develop an exception list of mobos that have ISA slots that don't
   show up under DMI.

My logic would then be: if the box has PCI, and DMI shows no ISA slots,
and the motherboard is not on the exception list, then suppress ISA 
questions.

This would be a kluge, but it would have the advantage that the exception
list is finite and can be expected to stop growing.
