I found out I have to add pccard_enable="YES" in rc.conf, now I find the
card but still does not want to load.
It errored out with:
wi0: wi_cmd: busy bit won't clear
wi0: mac read failed 5
first, I got that fixed with this patch:

        if (i == 0) {
                device_printf(sc->dev, "wi_cmd: busy bit won't clear.\n" );

Now it errors out with:
wi0 at port 0x240-0x27f irq 11 slot 2 on pccard2
wi0: mac read failed 28
device_probe_and_attach: wi0 attach returned 28

it seems to be some error at line 1134:
len = CSR_READ_2(sc, WI_DATA1);
