[panics]

I'm seeing both on this machine (desktop) here. A GENERIC + smbus + 
iicbb + iicbus kernel with a few modules specified for preloading in 
/etc/loader.conf bails out immediately (not even CLK calibration comes 
up) with "Fatal trap 12: page fault while in kernel mode [...]", then 
hangs. 'unload'-ing all modules from the loader and booting the plain 
kernel (+ acpi.ko) gets to atkbd0, then panics. No tracing possible, 
just more panics. The world was cvsup'd and built a few hours ago.
