Ok, I gave it closer look. It looks like acpi_pci_link_set_irq fails with
AE_ERROR, because: PCI interrupt link is disabled - \\_SB_.LNKD. So setting
hw.acpi.pci.link.*.*.*.irq=* gives no change to IRQ routing.
I tried also the patch submited by Alexandre Kovalenko, which overrides
acpi_pcib algorithm of choosing the first available interrupt, with setting
the choosen interrupt. The patch does its job and allows to use my PCCARD,
when ACPI is on.
Is there anything more, that I can do to investigate the problem?
