But the kernel itself has to know how to probe and initialize these devices
at boot time, correct? That information is implicitly exported via
/var/log/dmesg -- I'm simply suggesting that it be a little more explicit.

Some of the on-board devices on my Tyan Thunder are ISA.

Would that be feasible without root privileges in order to read kmem?

and brutalizes the mind: a habitual disuse of physical forces totally
destroys the moral [force]; and men lose at once the power of
protecting themselves, and of discerning the cause of their
oppression.
