Well most of those resources are present on every PC motherboard.

This will also be the case for 2.5.X. We already have the PS/2 keyboard
ported over to the input api. Since we can in theory have a USB system and
then later attach a PS/2 keyboard we have it so the resources are
allocated for PS/2 keyboards.

I still can't see a reason for allocating it before the device drivers 
could do that.

Any suggestions? Anyone?

What is the "input api"? Could You give me any URL to read?

If you write into those resources and they are absent, bad things
sometimes happen.  So, they are always added to the reserved-resource
list.  I already had this argument with Linus :)
