The original change in the hardware tables was for the benefit of a
benchmark.  Said benchmark isn't going to get run on mainline until the
next batch of enterprise distros drops, at which point the hardware
where this was done will be irrelevant for the benchmark.  I'm sure any
new hardware will just set this distance to another yet arbitrary value
to make the kernel do what it wants. :)

Also, when the hardware got _set_ to this initially, I complained.  So,
I guess I'm getting my way now, with this patch.  I'm cool with it:
