 Turns out the BIOS has more Processor Settings than fit on the
 screen, and scrolling down past the end reveals some additional
 settings including one called "X2Apic Mode".  After changing that
 from "Enabled" to "Disabled", NetBSD-current boots with working
 USB and SATA!  Thanks to Manuel for the clue.
 
 So there is now a work-around, but I'm leaving the PR open as the
 X2Apic mode is still broken.
