On amd64 -current, all of my PCI latency timer values read 0x00.  The
BIOS setting is 0xff, but I take it that different cards can have
different requirements.  However, thus far I haven't noticed that I
have any hardware which explicitly sets it.  Is this expected
behavior?

If someone could please sanity-check the following, I'd appreciate it.

Thanks,

--Blair

"The frivolity and boredom which unsettle the established order, the
vague foreboding of something unknown, these are the heralds of
approaching change.  The gradual crumbling that left unaltered the
face of the whole is cut short by a sunburst which, in one flash,
illuminates the features of the new world."  --G.W.F. Hegel,
_Phenomenology of Spirit_ 5:11
