The workaround would be if you could get ipx_configure compiled as a
64bit binary.
The problem is that 32bit programs running under a 64bit kernel have to
have the ioctl's translated, or atleast flagged compatible, so that they
get sent to the correct place in the kernel (just think about where a
32bit pointer is passed and the kernel driver expects a 64bit
pointer...nasty problems would occur without translation).
TO really fix it, the ioctl should be checked and added to
arch/sparc64/kernel/ioctl32.c, either as a compat ioctl (same size 32bit
or 64bit) or have a translation handler created.
