I'm still getting the &$%^ thing up! I have the 4200+ -- couldn't quite 
bring myself to go for the 5200+. :) I was in a hurry, so after living 
with freezes in the 2006.1 Gentoo LiveDVD, I tried Ubuntu Feisty Fawn-- 
which also froze. Debian Etch is the one that seems to be the most 
stable of the pure 64-bit distros out there so far, but it's frozen on 
me too -- while unpacking the 2006.1 AMD64 stage3 tarball, no less. 
Right now the machine is dual-booted Etch and CentOS 5, and if I can get 
the CentOS X configuration straightened out, I'm going to see how long 
*that* one can stay up without freezing.

I can't tell yet whether it's hardware or software, but I'm guessing the 
kernel at this point rather than hardware -- I have some 
/var/log/messages traces that don't look like hardware. Once I get a 
stable OS, I'll load Gentoo from it and do the real debugging. The 
2.4.20 kernel in Gentoo stable has to be better that the 2.4.18s the 
other distros seem to be carrying.
