This ends up describing the nitty-gritty details of the implementation instead of what users should take away from the options. Could we up level this a bit? How about this? intel_epb= [X86] auto (default) Work around buggy BIOSes to avoid excess power usage by forcing performance bias to "normal" at boot- time. preserve Do not override the existing performance bias setting. Useful if a previous kernel or bootloader's setting is more desirable than "normal". It's better formatted and uses the "(default)" tag instead of trying to explain it in prose. It also explains when someone might want to use the override instead of just explaining its function.
