We can't use dev->mod_index for selecting the interrupt routing entry, because it's not an index into interrupt routing table. It will be even wrong on a machine with 2 CPUs (4 cores). But all needed information is contained in the PAT entries for the serial ports. mod[0] contains the iosapic address and mod_info has some indications for the interrupt input (at least it looks like it). This patch implements the searching for the right iosapic and uses this interrupt input information.
