But what could be the cause for throwing this ACPI errors?
I've had acpi errors like the ones you list, that went away when I installed SL6.0 Before then I had to boot acpi=off. Your board is not SMP and does not support ACPI.
following errors were shown up(highlighted in bold & red color)
Since my mail reader translated HTML to plain text, I see nothing in bold nor in red. Generally, people on mailing lists prefer plain text to HTML mail.
Using APIC driver default ACPI: Unable to locate RSDP
Put 'acpi=off' in the boot line since your hardware has no ACPI.

You don't need an SMP kernel, you have 1 CPU with 1 core only.
PCI: No IRQ known for interrupt pin A of device 0000:00:02.0. Please try using pci=biosirq. PCI: No IRQ known for interrupt pin A of device 0000:00:03.0. Please try using pci=biosirq.
There's a suggestion I'd follow: boot line should have acpi=off pci=biosirq
Since you're building your own kernel, you can switch off SMP and ACPI. Likely APIC and IO_APIC also. Since you have only 1/2GB RAM, I'd switch off things I wasn't going to use.
