I thought I had this covered by using the eject option with cdrecord, 
but I must have been shoving it back in too quickly, or KDE's automount 
was being wacky.  Anyway, I swear it wasn't working when I made the 
post, but this morning I put the cd back in and I can see everything 
after all!  Well anyway, I know how to do command line cd-writing now.
