Yes. Let's not get into nit picking here. 16 address bits are there, and 
are decoded on some cards. Many cards only do decode 10 bits.

What I was trying to say is: "0x4300 is always an invalid ISA io port"
is not a correct statement (and that is how I read your message).

Anyway, if I understood correctly we are talking about a pcmcia card, which
can be mapped somewhere via a cardbus controller. Whether it decodes 10 or
16 bits of io addresses should be in the CIS info.
