[LinuxBIOS] More MCP55 hacking

[Lu, Yinghai]

If still has problem
1. 
#make the SB HT chain on bus 0, default is not (0)
#default SB_HT_CHAIN_ON_BUS0=1
2. 
Power off your target for a while. You may drive it nuts.

After commenting out these two options as you suggest, it looks like a
lot more devices are getting initialized; I had to increase HEAPSIZE
to 64 KB to avoid overflowing the heap.

Now, I'm getting an exception during PCI device init; see the attached
boot log.

Does it make sense that the same devices (e.g. 10de:0378) are showing
up on both bus 0 and bus 4?
