People cram Linux into machines with only 2M of ram, there are tons of
chips out there that are new and shipping in devices with less than 1M
of ram that would be great to have Linux running in them, but can't at
the moment.

So yes, in some systems it does matter, in others, it doesn't but that's
the beauty of Linux, it runs almost everywhere :)
