After latest ACPI patches by imp, I have found this related to pccard and
64k alignment:
Initial allocation for cbb is made at 0xf000000:
====
cbb0: <TI1225 PCI-CardBus Bridge> at device 3.0 on pci0
cbb0: Lazy allocation of 0x1000 bytes rid 0x10 type 3 at 0xf0000000
cbb0: Found memory at f0000000
cardbus0: <CardBus bus> on cbb0
pccard0: <16-bit PCCard bus> on cbb0
pcib0: slot 3 INTA is routed to irq 11
cbb1: <TI1225 PCI-CardBus Bridge> at device 3.1 on pci0
cbb1: Lazy allocation of 0x1000 bytes rid 0x10 type 3 at 0xf0001000
cbb1: Found memory at f0001000
cardbus1: <CardBus bus> on cbb1
pccard1: <16-bit PCCard bus> on cbb1
====
As previous cbb allocation is far of 0x88000000 (CBB_START_MEMORY), pccard
success:

However, I think that if we insert another pcmcia card (16 bits) it will
break, I have emulated it modifying hw.cbb.star_memory sysctl variable:
# sysctl hw.cbb.start_memory="0x88001000"
hw.cbb.start_memory: 2281701376 -> 2281705472
Then inserting card:
