Comment 18 for bug 399911

FYI
After installing the 2.6.32 kernal and following the very informative instructions detailed here: http://wiki.archlinux.org/index.php/Extra_Keyboard_Keys

I found that the following keys on the Samsung have scan codes but are not configured:

Fn+UP = 0x88 (e008)
Fn+Down = 0x89 (e009)
Fn+F2 = 0x83 (e003)
Fn+F4 = 0x82 (e002)
Fn+F5 = 0x84 (e004)
Fn+F7 = 0xb1 (e031)
Fn+F8 = 0xb3 (e033)
Fn+F9 = 0x86 (e006)

Not sure this helps but hey, i'm wandering in a dark forest here.
