# Small note:  we should prob consider using a DRM only tarball, as it will ease
#              some of the overhead on older systems, and will enable us to
#              update DRM if there are fixes not already in XFree86 tarballs ...

# Removing USE as soon as VIDEO_CARDS shows up in make.conf
IUSE="3dfx gamma i8x0 matrox rage128 radeon sis"

# Make sure Portage does _NOT_ strip symbols.  We will do it later and make sure

# We throw all necessary files into one folder and turn that into our tarball.
