I did some builds just using Debian Sid's native x86 gcc and binutils:

$ gcc --version
gcc (Debian 4.3.2-4) 4.3.3 20090119 (prerelease)
Copyright (C) 2008 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

$ as --version
GNU assembler (GNU Binutils for Debian) 2.18.0.20080103
Copyright 2007 Free Software Foundation, Inc.

This assembler was configured for a target of `i486-linux-gnu'.

Without your patch:

$ objdump -t com20020*.o | grep _ops
0000000000000000 g     O .bss	00000000000000a8 com20020_netdev_ops
0000000000000000 g     O .rodata	00000000000000a8 com20020_netdev_ops

So it is not powerpc specific.  (The powerpc toolchain (gcc 4.3.2m
binutils 2.19) was built by me from gnu sources, so it is not Debian
specific either.)

With your patch:

$ objdump -t com20020*.o | grep _ops
0000000000000000         *UND*	0000000000000000 com20020_netdev_ops
0000000000000000 g     O .rodata	00000000000000a8 com20020_netdev_ops

So, this could be a compiler bug?
