I don't have that much expertise with Kubuntu but it baffles me that it wouldn't work.
Personally, I think openSUSE, and SUSE in general for that matter, is the best choice for a 64-bit distro if you want it to run very very smoothly without codec problems and stuff. And I know that people will report zero problems with Ubuntu etc. and I'm sure that those claims are true, however since SUSE pioneered a lot of the AMD64 support that initially went into the Linux kernel, GCC and glibc I trust that their expertise with the AMD64 platform is very good.
The reason your onboard graphics card was not supported out of the box is because it's an NVIDIA integrated graphics card, and Novell nor the openSUSE project will not include proprietary drivers at all. Novell/SUSE employs a whole bunch of kernel developers and they were getting pissed off about the company that they worked for, in their opinion, violated their copyrights (Greg Kroah-Hartman is probably the most widely known of these Novell/SUSE employed kernel hackers). You can see an article he wrote about these issues here:
Myths, Lies, and Truths about the Linux kernel
(Greg Kroah-Hartman He might be a good candidate for an interview, what do you say Mr. Davila?)
So far, Ubuntu, and thereby also Kubuntu, have only included the kernel parts of NVIDIA and ATi's proprietary drivers as part of the default installation, you had to install the nvidia-glx package to get the X libraries and OpenGL implementation etc. etc.
In the next release they will also include the X libraries and enable the proprietary drivers by default, which I, personally, am not that fond of. I think that there should be ways to both respect the GPL, and make things easy for new users. But hey, what can I do, right?
I would recommend trying out openSUSE 10.2 if you havn't already. If the open source "nv" driver is not sufficient for what you require, and if you don't mind proprietary drivers (Which I do, when it comes down to my own personal use) you can find instructions on installing the proprietary NVIDIA drivers here:

Also, which versions of Kubuntu and openSUSE did you try? I say always try out the latest stable versions.
