Ok.

I don't know how it is used in NetBSD, the only difference I could 
observe is the sysctl parameter `machdep.booted_kernel' which is set to 
the file name of the booted kernel (or empty if the information could 
not be derived from the multiboot command-line).

Yes, it sure explains the problem, thanks!  I had a look at the 
multiboot command-line parsing in the NetBSD kernel: the first argument 
in the command-line is ignored (here `-z') as it is assumed to be the 
kernel file name.

Anyway, the above solution (duplicating the kernel file name) is simple 
enough. :-)
