No easy way, sorry. But you should run the Y2010 diagnostic tool to
see how many alarms you would have to reenter.

I worded the warning this way because shit happens, and I can't give
any 100% warranty that it won't :) And if it happens, the Newton is
bricked and can only be revived with a temporary ROM board swap. But I
have not gotten any reports of this happening during wider testing,
and in theory, it should be safe to use the patch.

What causes the bricking is an endless loop or other crash due to
applying a low level patch in the wrong place. This only happens when
you modify the patch package file itself. This shouldn't usually
happen, unless you develop patches :) This applies also to the
official Apple patches.

The ROM board swap causes the Newton to apply a very low level reset
(goes deeper than a brain wipe) during which the internal memory
including the patch memory is cleared. It might be possible to trigger
this also via the diagnostic pins on the motherboard, but I haven't
looked into that at all.
