I'm definitely not intending to be unreasonable, and I understand your
need to have the keyboard working all the way from the grub/lilo prompt.

I just don't like adding more module options to one that already has so
many it's hard to understand what they're used for.

How about simply this patch instead?

Setting autorepeat will not be possible on 'dumb' keyboards anymore by
default, but since these usually are special forms of hardware anyway,
like the DRAC3, this shouldn't be an issue for most users. Using
'softrepeat' on these keyboards will restore the behavior for users that
need it.
