You shouldn't need to list this explicitly.  The PCI scanning and power
management support is automatically loaded before the rtl8139.o module.

There should have been other messages before this.

What is the detection message?
What is the packet count when this happens?  ('cat /proc/net/dev/')
What does 'mii-diag' report?

Note that all PCI cards are "PnP".
PCI "PnP" is unrelated to the actions taken with ISA Plug-n-Pray.

This is not a problem with PCI cards.  In ancient times there were a few
broken SCSI drivers, but those have long since been fixed.

This points to a routing or firewall problem.

Note that the Linksys card requires a bus-master slot, so if it works
there is not a PCI slot problem.
