Question Need some help getting Gentoo stabilized on an AMD64 system

I just had a machine built from the ground up with an Athlon64 X2 4200+ on a Gigabyte M61P S3 motherboard, which uses the NVidia GeForce 6100 / nForce 430 chipset. I haven't completely ruled out flaky hardware, but what I'm running into seems more like kernel issues than that. The symptoms are random crashes, oopses, panics, freezes, etc.

As far as I can tell, the Debian Etch 2.4.18 i686 (32-bit) kernel is stable on this system. Debian Etch 2.4.18 AMD64 is less stable, not 100 percent in other words. The one I want to run, Gentoo 2007.0 AMD64, is a 2.6.19 kernel, and I can't keep it up more than about an hour or so before something breaks. I've tried the Gentoo 2007.0 i686 distro and it doesn't seem to be much better. It's not like Debian, where the i686 is stable and the AMD64 isn't.

One other note: *all* of them seem to be flawless during the install, even the AMD64 ones. There's something about the kernels on the install media that seems to always work. I've tried copying those configurations and building kernels with them, but that doesn't seem to help.

So ... what should I try next? Are there diagnostics I can use to rule out hardware issues? I've run memtest86 for 12 hours with no errors, and I think the stable i686 Etch pretty much rules out hardware anyhow. But where I want to end up is a stable AMD64 Gentoo system, which means a 2.6.xx kernel (they are up to 2.6.21, but I haven't been able to keep the machine up long enough to build it). Are there NVidia utilities I should be using, rather than the stock Gentoo stuff?
