Yes current has been working for a while with my NEC Versa 6030X. It uses
a TI1130. Basically it just emulates the VLSI 82C146 in default ISA mode
which I think the BIOS programs it for.

The port printed in the following message:
if (bootverbose)
printf("CardBus: Legacy PC-card 16bit I/O address [0x%x]\n",
io_port);
Emulation appears to be in a couple of modes:
ISA legacy -> look like an old style controller on the ISA bus.
Interrupt only -> the controller runs on PCI but can trigger
ISA interrupts with ISA interrupt glue.
