  Ah, which I have in my kernels.

  I'm wondering if the problem occurs anytime the kernel does a printf().  It 
seems
like each time it occurs to me, I was either doing something that did a 
printf(), or
something happened which resulted in a printf().  [The most recent was an 
informational
message from the CyberStorm Mk III SCSI driver.

  I haven't tried tracking it down yet.  My first step was going to be looking 
at
the kernel printf() and seeing if it does something that might interact with the
graphics chip.
