YhLu? explained:

move the apic before other 1. solve the onboard vga init problem, otherwise if mtrr is inited after VGA init.. 0xa0000, can be used by VGA 2. one apic id path is enough, other will be created automatically....., So if only one cpu is installed and there will be complaint about the non-exist static device...

We may only need northbridge with SB and SB in Config.lb

Ollie Lho explained: On board VGA cards do depends on these patch to work correct. By moving the apic cluster in front of other devices, the CPU cache will inited before on board VGA cards are inited. Otherwise, memory transaction will not be passed to the VGA cards.
