FWIW, I am running the x86_64 version of fedora 8 an an HP dv9208nr
Turion 64 X2 and have not had a single issue with lockups.  You might
look to ASUS for a possible BIOS update.

As a side note, I have a desktop machine based on an ASUS M2NPV with a
3800 64 X2 and was considering update it to the x86_64 fedora, I might
just wait now.
