You are badly mistaken.
On x86 workstation/server class hardware you might get away with it because
everything interesting is either standard legacy ports or PCI, and your
firmware/bios already took care of the really hairy bits.
On embedded systems there's often very little that can be automatically
detected, much less functionality provided by the firmware (You're lucky if
all your RAM is even turned on!) and you just have to know where stuff is.
