ibmnws boot failure

[Robert Swindells <rjs%fdy2.co.uk@localhost>]

The NetBSD/ibmnws port seems to be broken for 7.0 and -current, the
firmware generates a "Address out of range. File is bad or too large
for installed memory." error when trying to load a kernel, -6.1.5
boots fine.

There are different numbers of ELF sections in the kernels and an
extra program header in the broken one.

I have traced through the ncdcs utility and it still seems to be
calculating the checksum for the correct sections.

Also tried adding the second program header to the checksum calculation
but get same error.
