This may be the case, but between man page and output some terminology must have changed. I can't see any reference to anything like an MADT there. Does that mean that there isn't one, or that ACPI can't find it, or does the section APIC refer to/dump the MADT? Here's the complete output of acpidump -t, anyway:
MADT is the name of the table (Multiple APIC Descriptor Table or some such), but "APIC" is the 4 character signature of the MADT, hence seeing 'APIC' output from acpidump -t when looking at the MADT. Similarly, the MP Table is known as the MP Table, but the signature for the table that you search for in the BIOS is "_MP_".

Nothing strange here, and it is giving a 64-bit PA for the I/O APIC, albeit one that is < 4GB. One thing to verify is that the physical addresses listed here for the APICs (0xfec00000 and 0xfee00000) aren't included in the SMAP as valid RAM addresses in both cases. It might be useful to boot an i386 CD with 8GB in the machine to see if the MADT looks any different in that case.
