em0: Unable to locate IO BAR ( two 82542 cards )

I just updated to -current from today on a tyan 2895 (K8WE).   I applied the
new nfe MSI/MSIX support patches as well, however I don't think those have
anything to do with the problem below:

here's the pciconf -v -l output

Attached it the bootverbose output for this machine.
