This shows that in the - case the APIC is broken somehow (0.0 isn't a valid I/O APIC version).
You mean the + case, I suppose. Yes, that's what I suspected.
It would seem that the system has mapped RAM over top of the I/O APIC perhaps?
That's what I suspected too, but imp doesn't think so.
Actually, if the full version register were zero, it would not have had 24 IRQs (irqs 0-23 part), so I'm not sure what it is doing. 0.3 isn't really a valid APIC version AFAIK either, though I'm more familiar with the versions used in Intel APICs (usually 1.1, 1.2, or 2.0).
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.
Any suggestions about how to do so?
Boot with 4g or boot an i386 version and get acpidump -t output.
