Ah, yes. /etc/inittab rings bells.
Mine looks like this
# Default runlevel.
# System initialization, mount local filesystems, etc.
# Further system initialization, brings up the boot runlevel.

How much of that is specific to gentoo, I don't know, but if I remember correctly the salient bit is the
bit, it's telling the system that you want the default setup to be init 5 which is graphic interface, init 3 is what you have to use for just command line input (I recall that from installing/upgrading the nvidia driver).
<stunned>Bugger me! a proper suggestion rather than a general "this is where I found stuff about ......." type answers</stunned>
Erm, the only downside, is that you might have not been able to alter than unless you start a text editor after you logged in as root!
Which might not be the easiest of things to get your head round unless you have done text edits before (with one of the editors). My install (gentoo) uses one called "nano" by default, others might use "VI" or "VIM", or maybe "emacs". These may look like vvvvv basic word processors (which you can do with them), but they're not (unfortunately).
I'm guessing that your SuSE, might have installed VI as default, so you'd have to surf for some basics about using it, print them off, then boot into the SuSE install, and then log in as root (plus root password), the at the # prompt just type vi /etc/inittab and you should be able to make the change to get the system booting into kde (presumably) as default.
If your system has an nvidia based graphics card, you might also want to then check out the nvidia site for the driver (which is normally only available pre installed with "paid for" versions - well it is with mandrake, don't know about SuSE).
Erm, once you're happy with basic edit stuff in vi/emacs/whatever, it's less hassle, cos you don't have to keep swapping between user accounts and root, which graphically can be a pain/time consuming. You just open a terminal/konsole window, and at the $ prompt, type su and hit enter, you'd then be asked for the root p'word, and then it's just vi /usr/share/whatever or whichever file you need to edit.
Sorry if thats a bit of a shitty explaination, but I don't know how much IT knowledge/experience you have. It's about the best I can do without looking over your shoulder!
