The modules package contains the modules for:

-- the kernel
# We use the kernel pcmcia modules now. -P
# -- pcmcia-cs
-- DRM (direct rendering) modules for XFree86.
We mostly use the DRM modules included with XFree86
(as of 4.3.0), but still use the gamma.o.gz from the
older kernel-drm package since the driver in XFree86
is broken.
