and further again, PRs kern/32327 and kern/32328 describe the same trouble
with some older Thinkpads, with the suggested fix being to move the RBUS
area to 12-bit memory with

  options RBUS_IO_BASE="0xa00"          # orig 0x4000
  options RBUS_IO_SIZE="0x0ff"          # orig 0x2000

which does allow PCMCIA cards to work, but alas inserting a Cardbus card
caused a panic relating to lack of bus space, hrm.  This makes me think
perhaps I'm on the right lines and I don't know where the above values
come from but I've enabled a some options:

  options PCI_ADDR_FIXUP
  options PCI_BUS_FIXUP
  options PCI_INTR_FIXUP_DISABLED

these three by themselves made a slight difference in that the pci5 now
shows as "memory space enabled", then

  options CBB_DEBUG
  options CARDBUS_DEBUG
  options CARDSLOT_DEBUG
  options RBUS_DEBUG
  options PCMCIADEBUG
  options PCMCIAVERBOSE

brings a bunch more information. Is it possible to interpret this and work
out what suitable RBUS base/size values might be or do I have to guess?

During boot:
