i'd say file a bug with ATI, but they probably dont care.
This is actually due to the regparm patch; without it it compiles fine. But hey, then it will segfault when you try to load it. For now I just took the lazy path and disabled CONFIG_REGPARM in my kernel. The module naturally compiles and runs fine then.
It looks like this is no longer an issue in ati-drivers-3.11.1
closing it up then
