That is embarrassing...  I thought I had the realmode boot block but I 
was wrong.  I had a screwed-up bsdlabel from sysinstall at some 
point.  When I did 'bsdlabel -B', it failed to install the boot block 
at all but I ignored the error message, I guess. :-(

The bright side of this embarrassment is now I have warning-free 
bsdlabels on all partitions. ;-)

Sorry for the noise.
