Oh crapshit.... this is my fault...
Ok, throwing this one out to the gallery: Take a look at the new 00
rule in the udev package. The point is to export the blacklist to the
udev environment for use in load-modules (it should only be computer
once). Apparently, that rule is done poorly and it runs for every rule
run-through.

See mod-blacklist here: http://privat.archlinux.dk/bootchart.png
That should only be done once instead of the 28902373089434098 times it's run 8)
