Correct the RAM checking code to _not_ check the range from 640 KB - 1 MB, 

as that is not RAM but used for other stuff.

First try at PCI init added to src/mainboard/tyan/s1846/Config.lb.

Use a real payload (FILO) per default now.

Note: this cannot boot a payload, yet, but it gets a lot further now.
