I have tried your patched version of Netscape 2beta under NetBSD-current. 
There seems to be some incompatibilities left. Unfortunatly I don't have 
the experience to find said problem. Perhaps this extract from kdump can 
tell you something:

  9376 netscape-2.0beta CALL  sunos_open(0x221b,0,0x7)
  9376 netscape-2.0beta NAMI  "/emul/sunos/dev/zero"
  9376 netscape-2.0beta NAMI  "/dev/zero"
  9376 netscape-2.0beta RET   sunos_open 4
  9376 netscape-2.0beta CALL  sunos_getrlimit(0x3,0xf7fff568)
  9376 netscape-2.0beta RET   sunos_getrlimit 0
  9376 netscape-2.0beta CALL  
sunos_mmap(0xf7f80000,0x2000,0x3,0x80000012,0x4,0)
  9376 netscape-2.0beta RET   sunos_mmap -134742016/0xf7f80000
  9376 netscape-2.0beta CALL  close(0x3)
  9376 netscape-2.0beta RET   close 0
  9376 netscape-2.0beta PSIG  SIGSEGV SIG_DFL

On the other hand the distributed file netscape_dns works. I'm using
-r-xr-xr-x  1 petersv  users  4341760 Oct  7 05:32 netscape_dns

in case it makes any difference. Everything works nicely, until I try to 
open a java applet. I'm on an ELC.
