Got it - it's a simple copypaste mistake:

+ irq = dev->irq;
+ if (irq == IRQ_NONE) {
+ printk (KERN_DEBUG
+ "PCI parallel port detected: %04x:%04x, I/O at %#lx(%#lx)\n",
+ parport_pc_pci_tbl[i + last_sio].vendor,
+ parport_pc_pci_tbl[i + last_sio].device,
+ io_lo, io_hi);
+ irq = PARPORT_IRQ_NONE;
+ } else {
+ printk (KERN_DEBUG
+ "PCI parallel port detected: %04x:%04x, I/O at %#lx(%#lx), IRQ %d\n",
+ parport_pc_pci_tbl[i + last_sio].vendor,
+ parport_pc_pci_tbl[i + last_sio].device,
+ io_lo, io_hi, irq);
+ irq = PARPORT_IRQ_NONE;
+ }

If I remove the second "irq = PARPORT_IRQ_NONE;" it starts to load fine.
Will test later with a rela printer attached.
