Me too!

I examined the kernel in !Zap and found that at address &10411C there is a
branch to a blank area of code.  After examining SA-4740, I found that a
large section of the new kernel is missing.  In the old kernel, as far as I 
can tell, in the 'same' place (relatively) address &1038F4 the branch points
to a section of code located in the area of the hole.  Unfortunatly, the hole
is larger in size than the coresponding code from the old kernel so some new 
code is missing.  I did find however that if the branch is disabled
or returned then the kernel goes on to boot a little longer.
