One of the 'biggest' reasons is that there isn't any good 'default' to use for polling. I had code in the system that tried to guess previously, but I think it got ripped out. However, that code had problems in that it didn't work if FreeBSD had no driver for a particular piece of hardware, and assumed the IRQ was free even if it wasn't. Although, from hearing Mike Smith talk, the new VM86 and PnP code should have 'informed the kernel' of all such resources used, even if FreeBSD had no driver for the hardware.
