Yes. This is why I was asking if anyone had any other ideas...

Yes. My first crack at building a live CD image with new DDU bits
(which failed because I didn't add the /var/pkg/state tree and didn't
allocate extra space) generated a ramdisk size of 164831K. The one
created with these changes had a bootroot of 261215K.
It appears that a 512Mb system cannot boot the second image. It's been
stuck at a black screen for several minutes now...
