Yes, but I'm not sure the Linux boot code is able to handle such
exceptions -- it's not in a very durable state at that point in it's
life, and error checking is kind of low priority.

In any case --  in the interest of Science, here are the results of the test:

1) A full Linux IPL deck puched onto real cards for Debian 3.0 is
   a little less than 23000 physical cards, as someone already
   mentioned, just about 2 cases of cards.

2) Attaching the physical reader to the virtual machine as 010 and
   doing an IPL 010 CLEAR *does* successfully start and clearly gets
   to the point of reading in the initrd.  I didn't try to do a
   complete IPL for time reasons, but when I stopped the process, it
   had read about a third of the deck, and displaying storage showed the
   right contents.  This took about 40 minutes.

3) At the rate it was going, I'd make a guess that it would have taken
   another hour or so to complete reading the deck.

I now have more note cards than I'll be able to use in a
*lifetime*...8-)


Better living through Science,
