   Odd.  Netscape runs for me.  I have an ELF kernel and the new bootblocks,
and obviously a new ELF world.

   I believe the boot blocks contain the software required to access the disk
and boot the kernel.  Obviously you'd need new boot blocks if you'll be
trying to run a kernel that the 2.2 blocks don't understand.
