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.
