Mutlimedia Keys (FN Keys)

After upgrade from 11.04 to 11.10
multimedia keys (FN combinations) stopped to work at HP Pavilion dv6
only showing ugly screen looking like crossed touchpad.

when i try to remap keyboard shortcuts in gnome settings i could see that code is correct and gnome recognize key.(xf86audioplay etc). but stil no action after remap.

if anyone know how ti fix it or its just new bug in 11.10

PS xf86volume up and x86volume down keys works fine. but i think they're functioning via acpi.
