Yes, you're right. LB accidentally configured the integrated ethernet
card's memory base address to be 0xfec00000, and that made cpu
accessing memory at 0xfec00000 problematic. Wired since the worked MB
has exactly the same problem but it has no problem accessing
0xfec00000 as IO-APIC memory only linux cannot make the ethernet card
work without changing its base memory address.
