If CONFIG_UNUSED_SYMBOLS is not set with a 2.6.25 kernel, fglrx returns fglrx: Unknown symbol init_mm and doesn't load. Reproducible: Always
Now, in the latest ebuild the check is made but as an ewarn, should not be an eerror and add a die?
9.6 dont need the check anymore and it is our target so wontfix. If you have card not supported by them rather switch to xf86-video-ati. Guide describing the approach will follow.
