All the ISA cards are in EISA mode (set in 3c5x9cfg.exe utility).
IRQs are assigned by the EISA bus (set by EISA configuration utility).
If any of the ISA cards are in non-EISA mode, the some of them
does not work at all, starting from EISA BIOS config during boot.
So I can't switch the cards into PNP mode.

Also, I tried setting the cards manually with 3c509 module
parameters.  The only parameter one can tweak is irq=,
but it seems the parameter is ignored -- I tried
 modprobe 3c509 irq=15,7,5,12
but it still detects only the EISA card with irq=12, just
like without irq= line at all.
