Possible keymap issue with kernel 2.6.15-rc5

[James T. <ja...@nu...>]

I decided to replace my Debian install in favor of Gentoo.  After getting my system up and running using gentoo-sources kernel 2.6.14-gentoo-rc2 pbbuttonsd was working great, all buttons and backlight control worked great.  I decided to upgrade to vanilla kernel 2.6.15-rc5 so I could try out the airport extreme card drivers recently released.  They work great, for anyone wondering, but to my real issue now.  After upgraded to kernel 2.6.15-rc5, blankscreen still works, but the keys to control the backlight, sound and eject don't work anymore.  I used the same .config from my previous kernel, and doubled check to make sure everything was enabled.  Anyone have any ideas?  Could the keymap have changed so fn+f1 and so forth show a different keycode.  I tried out showkey but can't get it to output anything besides a 0xXXX value.  Does the XXX corrispond to the normal XXX in the pbbuttons config?  Thanks for your help.
