Yeah, I do too. I originally thought that the Debian kernel was broken, 
but if you leave it long enough then it does proceed to the end. My 
guess is that there is a bug in the OpenBIOS console which is obscuring 
the output.

The first part of the boot below happens reasonably quickly; then like 
you the console puts out lots of junk before it returns:

  erase them! If you haven't made backups yet, remove the rescue CD from
  the drive and press L1-A to get back to the OpenBoot prompt.

It looks like your latest set of OpenBIOS patches has helped with the 
serial port, since before these the buffered portion (i.e. the part that 
I imagine is supposed to appear at the time when the blocks are being 
drawn on the console) never used to appear. Not quite sure why some of 
the entries are duplicated though.

Finally, the command line I am using is:

./qemu-system-sparc64 -cdrom debian-504-sparc-netinst.iso -nographic -boot d


HTH,
