Are you really trying to say that the kernel reserves 1 gig of memory?
That's majority excessive...
For example, my home server:
Memory: 2032508k/2071552k available (3179k kernel code, 37192k
reserved, 1466k data, 232k init)
that's 3.1 megs used, the reserved it a lot higher, but that includes
the 32 meg ivtv buffer I have on the box, so it's rather inflated.
no kernel should ever, ever, ever use a full gig for itself unless you
have a *very* specific reason.
