FYI, I currently have debian-pure-amd64 running successfully on a Gigabyte K8NSNXP-939 motherboard. However, there is one caveat. The memory had to be configured as single-channel instead of dual-channel. I am no hardware export, but there is a lot of chatter on other forums about problems with the memory access on this Gigabyte board and others using the new AMD 939 pin chip with the integrated memory controller. When configured with dual-channel memory, I experienced random segmentation faults, about every half hour, using both the 64 and 32 bit debian installation. Maybe with some bios upgrades or future releases of this mother board, it will become stable using the faster dual-channel memory as it was designed for.
