Yes, the old mbr was the problem. I wiped the "stock" mbr. I was previous using 
the key for booting a olpc machine and the mbr must have been left over from 
that. I assumed that livecd-iso-to-disk took care of the mbr. I guess that is 
what I get when I assume.

I have images from a livecd-creator iso working in the USB flash. I just wished 
that the kernel-debuginfos required by systemtap were not so huge. Only have 
700MB of room on CD and the kernel-debuginfo takes a lot of space.
