I only use the old cv.  Its limitations haven't hit me yet, and the new
one, doesn't do the big kernel correctly.  Agreed.

I suggest that if you cant build a working kernel thay you:
1. make sure that you increase the size of the stack (chmem +20000) of 
sttools/build.  Besides just failing, walking on this stack will change
the code in minix.img. BAD!

2. Start simple.  One of the goals of addind the HAVE switches in h/const.h
is that you can turn them ALL OFF.  This produces the original kernel.
Try it; then add in features one at a time.  Thats how I check it.
