1215n-sabayon valentina # modprobe bbswitch FATAL: Error inserting bbswitch (/lib/modules/3.2.0-sabayon/kernel/drivers/acpi/bbswitch.ko): Invalid module format This does not allow to power down the discrete GPU when unused. Recompiling from our overlay makes this working, so I guess it just needs a recompilation.
Packages with kernel modules need to have a kernel tag assigned in Entropy AFAIK.
