Meanwhile I had the idea to run objdump -t on the kernel and on
nfs_boot.o. It looks like a compiler bug. The compiler (GCC 3.3.2-nb1,
updated monday) placed some global variables into a .ident section
instead of .data. Similar to find_port from sys/netinet/ip_h323_pxy.c,
but this is a function not an int.

objdump -t ip_proxy.o | grep ident
00000000 l    d  .ident 00000000 
00000000 l     F .ident 00000168 find_port

nfs_boot.o:     file format elf32-big
