Well, option 2 does disable APIC.  The acpi hint alone does not.  So, it seems 
that you have problems if you use APIC, and don't have problems if you 
disable APIC, and ACPI has no real bearing.  It sounds like perhaps your BIOS 
is not giving us the right information about how the interrupts are 
connected.  Have you tried plugging the devices into mpt0 rather than mpt1 
btw?  As it is, you can try to override your BIOS to set the IRQ for mpt1 
manually to try to figure out what IRQ it is really routed to.  (If there is 
a BIOS update that might also fix this problem.)  I'd try IRQs 24-47 (on your 
second ioapic) first.  You can try an IRQ by setting this in the loader 
before boot (this would use IRQ 24 for mpt1):

hw.pci3.3.INTB.irq=24
