I installed Gentoo on a HP Laptop, Xfce desktop, openrc, grub0, genkernel with "Desktop Profile". All works fine, like my two desktop PC's. The extended function keys and other laptop specific items don't work. It appears the problem is caused by the Gentoo Kernel.

I tried OpenSuse 13.1 and Sabayon 10 and 14.11. They work fine with all laptop related functions active.

The exptended Function Keys will work if I use the genkernel-x86_64-3.5.0-sabayon kernel and initramfs from the old Sabayon 10 installation CD. I copied the .config file from from the Sabayon CD to /usr/src/linux, loaded the Sabayon .config file and recompiled the current kernel. Does not work.

I just can't figure out how to configure the current Gentoo kernel so the extended function keys and laptop functions will work.

Are you referring to the Fn keys http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c02035108 or to some additional buttons (Unknown key pressed ...)?

That's what I am referring to.
Bios "Action Key Mode" is set to "Disabled".

With the Gentoo Kernel pressing Fn plus F2 or F3 nothing happens. With the old Sabayon Kernel or OpenSuse 13.1 and Sabyon 14.11 the display intensity decreased or increases and pressing Fn plus F12 keys switches the Wireless LAN between On and Off.
