There is a broken kernel module, due to which I can not even load the OS, so I can not delete or fix it. Is it possible to skip this module at boot, using the kernel's parameters or something?

Blacklisting the module as mentioned in the previous answer is the best way to completely avoid a kernel module. Aside from blacklisting, there is no generic way to disable a module.

Some Linux distributions do provide kernel boot parameters to do things like this.

  • In Arch Linux, load_modules=off forces udev to skip auto-loading. This would allow you to boot without loading modules, blacklist a module that's causing trouble, and reboot normally without the troubled module loading.
  • Knoppix has a long list of extra boot parameters (aka "cheatcodes"); these are a mix of normal kernel boot parameters and Knoppix-specific extras.

For further info, see the Kernel Parameters documentation. There are parameters for disabling specific subsystems. For example:

  • nousb disables kernel USB support
  • cgroup_disable=[name] disables a particular controller; however, "memory" is the only example specifically supported
  • libata.noacpi disables ACPI use in libata (SATA controllers); this is an example of passing a module parameter via the kernel

You should be able to either add it to /etc/modprobe.d/blacklist, or blacklist 'modulename'

this will work but requires booting to another kernel (if available) or a LiveCD system. – quack quixote Jun 17 '10 at 17:41
