You have booter 1.x. You need booter 2.x which is available from:

ftp://ftp.netbsd.org/pub/NetBSD/arch/mac68k/installation/misc/

The file you need is either BSD_Mac68k_Booter.bin or Booter2.0.0.sea. 
Booter2.0.0.sea contains the manual along with the booter which 
BSD_Mac68k_Booter.bin just has the booter.

The error comes from the fact that kernels are now in ELF format while 
they were in a.out format before. Only the new 2.x booter supports the 
ELF format. Hope that helps.
