i get:
===
#include <arch/pirq_routing.h>
const struct irq_routing_table intel_irq_routing_table = {
        PIRQ_SIGNATURE, /* u32 signature */
        PIRQ_VERSION,   /* u16 version   */
        32+16*5,        /* there can be total 5 devices on the bus */
        0,           /* Where the interrupt router lies (bus) */
        0,           /* Where the interrupt router lies (dev) */
        0x1c00,         /* IRQs devoted exclusively to PCI usage */
        0,         /* Vendor */
        0,         /* Device */
        0,         /* Crap (miniport) */
        { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }, /* u8 rfu[11] */
        0x78,         /*  u8 checksum , this hase to set to some value that would give 0 after the sum of all bytes for this

        {
                {0,0xa0, {{0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xdeb8}, {0x1, 0xdeb8}}, 0x1, 0},
                {0,0x98, {{0x1, 0xdeb8}, {0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xdeb8}}, 0x2, 0},
                {0,0x50, {{0x4, 0xdeb8}, {0x1, 0xdeb8}, {0x2, 0xdeb8}, {0x3, 0xdeb8}}, 0x3, 0},
                {0,0x68, {{0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xdeb8}, {0x1, 0xdeb8}}, 0x4, 0},
                {0,0x8, {{0x1, 0xdeb8}, {0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xdeb8}}, 0, 0},
        }
};

which is quite different from src/mainboard/via/epia-m/irq_tables.c:
===
                /* ethernet */
                {0,0x90, {{0x3, 0xdeb8}, {0x4, 0xdeb8}, {0x2, 0xdeb8}, {0x1, 0xdeb8}}, 0x1, 0},
                /* usb */
                {0,0x80, {{0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xdeb8}, {0x1, 0xdeb8}}, 0x2, 0},
                /* pci */
                {0,0xa0, {{0x1, 0xdeb8}, {0x4, 0xdeb8}, {0x3, 0xdeb8}, {0x2, 0xdeb8}}, 0x3, 0},
                /* audio */
                {0,0x8d, {{0x4, 0xdeb8}, {0x3, 0xdeb8}, {0x2, 0xdeb8}, {0x1, 0xdeb8}}, 0x0, 0},
                /* 1394 */
                {0,0x68, {{0x4, 0xdeb8}, {0x3, 0xdeb8}, {0x2, 0xdeb8}, {0x1, 0xdeb8}}, 0x3, 0}
===
but almost the same as (also from src/mainboard/via/epia-m/irq_tables.c)
===
#if 0
        {
                {0,0xa0, {{0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xdeb8}, {0x1, 0xdeb8}}, 0x1, 0},
                {0,0x98, {{0x1, 0xdeb8}, {0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xdeb8}}, 0x2, 0},
                {0,0x50, {{0x4, 0xdeb8}, {0x1, 0xdeb8}, {0x2, 0xdeb8}, {0x3, 0xdeb8}}, 0x3, 0},
                {0,0x68, {{0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xdeb8}, {0x1, 0xdeb8}}, 0x4, 0},
                {0,0x8, {{0x1, 0xdeb8}, {0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xdeb8}}, 0, 0},
                {0x50,0, {{0, 0}, {0, 0}, {0, 0}, {0, 0}}, 0, 0}
        }
#else
===

hmmm...
who did the src/mainboard/via/epia-m/irq_tables.c code?

does this mean that if i unplug the dual nic, that i cannot use the
same linuxbios anymore?
