I do have ACPI on. I believe booting into -s mode, manually mounting and fsck-ing the slices, and adding the two kernel paramenters to /boot/loader.conf as you suggsted has sorted me (or, at least, alleviated the system of kernel errors). I used your parameters ver batim; I will need to understand how the values relate to physical memory (only 320MB) before I tinker with them. Thanks again, ~John
