Comment(by colin):

 Replying to [comment:2 anevilyak]:
 > I stand corrected, we do have a cardbus driver (c.f. ticket #1086).
 Listdev however will currently only list what's on the PCI bus itself, it
 doesn't probe any other busses.

 Ticket #1086 is somewhat misleading. In general, there is no CardBus
 support in the sense of anyone can use hardware with it.
 What ticket #1086 states is, that during PCI initialization CardBus
 bridges are detected (so they showup in listdev) but not configured in any
 way (no powering up, no scanning of connected devices, etc.).
 Detection of CardBus bridges needs special code during PCI init (CardBus
 Bridges have their very own PCI header format) this is what ticket #1086
 refers, to. Going to add this information to #1086 to prevent future
 misleadings.
 Thus leaving this ticket in enhancement state is valid.
