Ok, I managed to find the hardware list while looking for another 
problem. At least I have a clue what the hardware is. The hardware for 
the Acer Aspire 5100 can be found at:

http://hardware4linux.info/server/system/347/

The PCI bridge 5a37 is part of the RS480 bridge, and the 0551 error is 
from SD/MMC card reader controller. Now I need to get the fixes.
