Arch power! (module blacklisting capabilities)
In Archlinux, you can already disable modules from being loaded by blacklisting them in rc.conf (prefix the module name by “!” in the MODULES array).
Now you can do that at boot time! Tada!
You can blacklist modules at boot time with the disablemodules boot parameter.
disablemodules=foo1,foo2,etc. to your kernel line (where foo1,foo2, etc. are the modules you want to blacklist).
This feature is very helpful when you know that certain module causes trouble and you are doing an install or fixing a system.
This feature will most likely make it into 0.8 release (whenever that is! :P).
