For the same reason normal PC's still like to: no technical reason, except for the fact that system vendors like to hide bugs and quirks by having magic stuff in ACPI or PnPBIOS to tell the OS "hands off" or "this is how to route this strange irq". It's like ACPI: it would be a whole lot better if the hardware was just standard and documented and didn't need any magic configuration tables and strange code snippets to do magic acts of perversion. But sadly, it ain't so, and PnP and ACPI are there as imperfect ways of doing what needs to be done. Of course, as with most system vendor crud, some BIOSes are more imperfect than others.
