I just installed 2.6.15-gentoo-5, so I have a much more recent kernel. This strange behavior still happens. I forgot to mention that I'm using this on an P4, and the kernel is compiled 64-bit.
I sent Ben a copy of the whole dmesg output. Here's the portion that everyone else might be interested in:
