Hmmm. I don't think that this applies to me. I ran an
AMD64-modified version of memtest for about 3 days straight and
got no errors.

If you are interested in trying my current 64bit kernel
(2.6.1-rc1 + x86-64 group fixes), which is monolithic and has
working gigabit and aic79xx, let me know and I can post mine
