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.
