1. Features of mahogany.

The code can run on the Mahogany board, which is one of sample boards
made by AMD. Its major features are:
 CPU (only K8 system):
  * AMD AM2+
  * AMD Athlon 64 x2
  * AMD Athlon 64 FX
  * AMD Athlon 64
  * AMD Sempron CPUs
 System Chipset:
  * RS780E
  * SB700
 On Board Chipset:
  * BIOS - SPI
  * Azalia CODEC - Realtek ALC888
  * LPC SuperIO - ITE8718F(GX).
  * LAN - REALTEK 8111C
  * TPM - SLB9635TT1.2
 Main Memory:
  * DDR II * 4 (Max 4GB)
 Expansion Slots:
  * PCI Express X16 slot*2 (PCI-E X8 Bus)
  * PCI Express X4 Slot*1
 Intersil PWM:
  * Controller - Intersil 6323

2. The ACPI feature is already added. I suggest that firstly we can test
the board without the ACPI by setting the HAVE_ACPI_TABLE as 0.
With Rev F processor, the HT link can only work in HT1, whose max
frequency is 1GHz.
