Below is a comparison with a cold-booted laptop using the same card
inserted (still acpiphp as in $subj).

Interesting is that on the lines starting with + sign (cold booted with
an empty card slot, the hotplug insert via acpiphp on 3.7.10 kernel with
pcie_aspm=off) and reg 10, 18, 20, 30 the hex values are zeroed in their
upper bits. Is this same as
'[virtual] Expansion ROM at f0000000 [disabled] [size=512K]'
in lspci ouput?

I will let you breath now for a while. ;-)

Below is merely another example of the same thing but with MediaCardReader enabled
in BIOS.
It is in turn being "reset" by ehci_hcd in the end. I believe this is why I observed
that the media card reader sometime appears in the system only after I plugged into
the express card slot a card (not sure from top of my head if that only only with
this eSATA card or even other cards, could be that this is sata_sil24-specific).
I gather the Media Card Reader is just an innocent victim as I haven't found
lsusb/lspci diffs when I have the card reader or disabled in BIOS, except that device
being one. Why other USB-bound devices, like the UVC Camera, are not being reset as
well by ehci_hcd, I do not know. Maybe usb-storage or ums-realtek looks only for
disk-like devices? Or sata_sil24 looks for disk-like devices to reset them?
