All those busses conform to the HP IO ADC and thus could be
considered the same type of bus. Except for LASI, the above makes
sense to me.

LASI isn't a bus. This would be a candidate for "platform device"
since it's bridge-like device with integrate sub-devices.
EISA bridge chips might be a similar case.

I don't understand "platform devices" vs "PCI devices" unless we
are talking about "custom", arch specific bridge chips.
A GSC device is a GSC device regardless of which board it's soldered to.
That's not the case for PCI?
