[ltp] Redundant entry in serial pci_table

[Efthym]

Hi Sabine,

Had the same problem with my T21 installing Fedora. It was getting stuck  
on the IRQ assignment as well. Unfortunately, the problem was only solved  
with  a replacement of the mini-pci.
You can try to verify that it is actually the modem/eth0 by opening the  
cover for the mini-pci, disconnecting one or the other and trying to boot  
without them. If the installation goes through, then you found the culprit.

Hope this helped.
