Re: Bug#497230: [alpha] legacy and generic package descriptions

Legacy mode is necessary ONLY for MILO machines - all
machines running SRM will work fine without legacy mode.

And yes, there's more of a "gap" between low memory stuff and
the kernel when in non-legacy mode, but that doesn't mean it goes
unused - the kernel can use it for paging, or static space, etc,
just like any other part of its address space.

That's not to say it DOES use it; it's been long enough since
I looked at that area of the code for me to be unsure; anyone
else have any insight?
