If you install (open)SuSE, Ubuntu, Fedora or something as popular as them, chances are your hardware works after the installation without much extra work. Things that usually need more attention include wireless cards (in some cases, not nearly all the time), webcams (I have never had one, so can't help you out with that), extra buttons in some cases (like "help" => custom functionality) and perhaps some exotic cadgets that aren't on every machine (if a cadget is found on nearly every pc, chances are somebody has written drivers for it for Linux and they're already there when you install GNU/Linux operating system).
First get the operating system installed if you want that, then see what doesn't work as you'd expect, describe it here, drink a cup of your favourite beverage and see if somebody posted an answer by then
most problems are easy to solve, especially with aid from longer-term users. Nowadays GNU/Linux operating systems such as SuSE are easy to install, so that shouldn't be a problem..but if you are in doubt, ask first by all means.
