Two more observations: (adding to my previous below email)
1) Centos 5.6 also showing the same ACPI errors as in CentOS 5.5
2)BIOS-E820 map has a difference in the first line: (0000000000010000
instead of 0000000000000000)
================================
- Centos-5.3 BIOS-E820 memory map is:
BIOS-e820: 0000000000000000 - 000000000009e000 (usable)
 BIOS-e820: 000000000009e000 - 00000000000a0000 (reserved)
 BIOS-e820: 00000000000e0000 - 0000000000100000 (reserved)
 BIOS-e820: 0000000000100000 - 000000001fee9000 (usable)
 BIOS-e820: 000000001fee9000 - 0000000020000000 (reserved)
 BIOS-e820: 00000000fff00000 - 0000000100000000 (reserved)
0MB HIGHMEM available.
510MB LOWMEM available.
================================
- Centos-5.5 BIOS-E820 memory map is:
BIOS-e820: 0000000000010000 - 000000000009e000 (usable)
 BIOS-e820: 000000000009e000 - 00000000000a0000 (reserved)
 BIOS-e820: 00000000000e0000 - 0000000000100000 (reserved)

================================

Not sure this is why ACPI's root table is not able to find.

Any comment/suggestion/pointers are really needed/appreciated.
