Actually, using multiboot in NetBSD's boot loader gives the kernel message:

multiboot: Information structure flags: 0x0000000d

which means in particular that the flag MULTIBOOT_INFO_HAS_ELF_SYMS is 
not set.  Hence the function multiboot_ksyms_addsyms_elf does nothing, 
and this function is supposed to set up the initial kernel symbol table 
(as per comment).

So, as I understand it, this problem is not a bug, but a missing feature 
in the multiboot implementation of the NetBSD boot loader.  In -current 
and netbsd-5, the file sys/arch/i386/stand/lib/exec.c contains code 
related to this, but this code is enclosed in a #if 0 ... #endif.
