I tested that iso on my 6100 (I actually copied the files off of it
onto an external SCSI drive to avoid wasting a CD-R).

After showing some juicy logging info when diagnostics is turned on
(due to me coincidentally holding down command-shift-option-delete-5
to boot the external drive), it displays 3 tux logos indicating
different boot options.  By hitting the right arrow a few times, it
shows that the Debian Sarge installer boot option is selected.  After
pressing enter, a lot of good stuff seems to happen (brackets added by
me):

After that, the screen is filled with black-and-white garbage, and
there are no apparent signs of life after that.  The numlock,
capslock, and scroll lock lights remain off, and the capslock light
does not turn on when the capslock key is pressed.

I did try the miBoot route back when I had a Debian Woody system
already installed and working via MkLinux.  I had the same problem
with the included kernel image, but when I substituted some other
kernel (possibly the Debian Woody kernel), it actually did boot up.
However, it was faily compared to using MkLinux, though I don't
remember the symptoms.  They might have been IO errors, X not
starting, networking not working, and maybe even a kernel panic.

Hope that helps!
