This shows that in the - case the APIC is broken somehow (0.0 isn't a valid I/O APIC version). It would seem that the system has mapped RAM over top of the I/O APIC perhaps? It would be interesting to see the contents of your MADT to see if it's trying to use a 64-bit PA for your APIC. The local APIC portion seems ok though.
