I found this patch (by searching the mailing list archives for cvs-all
postings with the date Feb. 4, 2005), and it applied cleanly, but now syslog
is getting spammed with:

microuptime() went backwards (443643.141593 -> 443642.210394)
microuptime() went backwards (443647.382021 -> 443640.104932)
microuptime() went backwards (443648.320102 -> 443847.981025)

...ad nauseam.  It looks like the timecounter code needs to be modified to
account for the temporal distortion.  Either that or maybe my crystal ball
interface isn't working properly (usbd has been kind of flaky about
detecting it lately).
