OK. But here's the problem. What difference will removing 2GB of Ram
make any difference once the machine is back up and running with 4GB of
RAM. I would feel better if the PCI bus actually saw the card. I will
try doing a few things tomorrow:

1) Try moving the 3Ware card from the 133MHz slot to one of the 66MHz
slots and see if linux sees the card.
2) I will possibly try removing 2GB of RAM and see if things magically
start working :)
3) I'll poke around in the BIOS some more and reread the kernel
parameters list again and see if something obvious appears.
