i wonder what the different between 
offs = ( pci_read_config16(dev, pos + PCI_CAP_FLAGS)  & (1<<10)) ?
PCI_HT_SLAVE1_OFFS : PCI_HT_SLAVE0_OFFS;

and

offs = ( (pci_read_config16(dev, pos + PCI_CAP_FLAGS) >> 10) & 1) ?
PCI_HT_SLAVE1_OFFS : PCI_HT_SLAVE0_OFFS;

It won't configure the second 8131 correctly, still.

It boots fine though if I put my swap_links macro back in and call it
for the second 8131

#define swap_links(bus,dev,fn)          \
do {                                    \
        unsigned reg1,reg2;             \
        device_t b=PCI_DEV(bus,dev,fn); \
        reg1=pci_read_config32(b, 0xCC);        \
        reg2=pci_read_config32(b, 0xD0);        \
        pci_write_config32(b, 0xCC, (reg1 & 0xffff00ff)|(reg2&0x0000ff00)); \
        pci_write_config32(b, 0xD0, (reg2 & 0xffff00ff)|(reg1&0x0000ff00)); \
} while(0)
