I am experiencing the same problems on my Samsung P55-Pro, which indicates that these models probably handle those things in a similar way. I can add something to the backlight problem: When resuming from suspend to disk the backlight usually is not at full brightness, but when booted with ac plugged in it can be set to full brightness. However, I cannot change the panel brightness (ie. lower it) after setting it to its maximum. Also the brightness indicator that seems to come with gnome always shows that the brightness is at 0 percent when trying to change it, even though the brightness is at maximum. Additionally I guess it's worth noting that this system does not come with an Atheros based wifi adapter but rather an Intel one (IPW3945), so the wifi switch problem is likely unrelated to the adapter itself. I am well aware that this is not fully related to the NC10 and the exact problems you are having with it, but maybe someone has a fix for my model that also works with yours or vice versa.
