X won't start after emerge --world update

[smarthur@riseup.net]

i have been successfully running gentoo and Xorg on my 15" aluminum
powerbook for quite some time now. however, after i ran emerge --update
world a few days ago, X refuses to start up. i tried recompiling my kernel
and going over my xorg.conf file, but can't find anything amiss. when i
run startx, the screen goes black like it always does on startup, the
cursor appears, and then it crashes. here's the output after it crashes:
