Oh - for the curious - you may append 'memmap=' to the kernel options
to reserve blocks of RAM.

In may case, my /boot/grub/menu.lst has this line now:
kopt=root=UUID=[some stuff] memmap=140M$580M memmap=140M$1600M ro

After 'sudo update-grub' it adds the memmap options.  Psuedo-syntax is
[howmuch][unit]$[where][unit].  So I'm sitting on 140 megs starting at
580 megs and 140 megs starting at 1600 megs.

Of course, not a good/permanent solution, but at least I can search
for new RAM online w/o constant segfaults ;)  'free -m' does report
the missing ~280 MB.
