Comment 4 for bug 183818

It seems SET_MODULE_OWNER() is obsolete and was removed from the kernel. I could not find when it got removed, but in the 2.6.24 changelog there are entries where it got removed from other netdrivers, see http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.24

Removing line 254 in rtmp_main.c the compilation succeeds. I've down little testing with the rt2500 driver (after blacklisting rt2500pci) and it seems to work fine now on hardy-rc. However, i am no kernel dev, and it only works for me as a workaround.
