Sup. First of all, I have used SuSE (still do) on several boxes.
8.0 is by far the most stable of the SuSEs. (That I have found, other than 7.3 for sparc but thats a differnt story all together)
I currently have SuSE running on a number of boxes ranging from a really really old 486x166MHz to the most up-to-date i386 archs out there.
Personally, I use NOTHING but AMD. Intel (to me) is like the M$ horde of hardware. It's fine for multimedia, and PC snooping, but not for an actual computer that requires power.
As far as your problems:
I wouldn't use Konq. It's just not worth it. SuSE comes shipped with a crap load of other proggies that can do as much and more than KingKonq.
The "locking" up problem is most likely your SiS chipsets. SiS is known to have buggy equip. On-board works fine with SuSE, but I still normally frown on on-board. You just get better perfomance and quality from external to mobo parts. At least in my world.
If you like, I'll send you a detailed list of all the systems I've used. I have actually used a mobo with SiS onboard for SuSE, but that was a while back.
