USB mouse still doesn't work on lion, but it works on tiger, and this kind of symptom cannot be reproduced on ia32 box.

There is only 1 PRT entry in DSDT for bus 0, slot 3,  but it is for pin D  not for pin B . And the error message reflect that fact. 
This error is for device 00:03.3 --SMBus. I don't know how to test that device.
Actually 2.6 will call acpi_pci_irq_derive try to derive IRQ from parent bridge, if nothing found from PRT List, But 2.4 will not do that.
Actually, acpi_pci_irq_enable will not be called in 2.4. Maybe this is a issue. But it will not help this case.

Since VGA console driver faile to allocate that port range,  why it still can work?
Does it mean 0x3c0-0x3df is inessential to  VGA console driver.
