Live init: add 'blacklist' bootparam to prevent loading of kernel driver(s).
Any kernel modules mentioned here will be added to the modprobe blacklist. This will help out people who need to blacklist the nouveau driver, for instance if they have a too-new computer. Syntax: blacklist=mod1[,mod2[,...]]
