Bad idea, the kernel crashes & burns when I use mem=256, I had to boot
2.6.20-rc5-6 single to get back into my machine, very nasty. Remember I
use an onboard graphics controller that has 128MB of RAM allocated to it
and I believe the ICH8 chipset also uses some memory, in any event mem=256
causes the machine to lockup before it can even get to the boot/init
processes, the two leds on the keyboard were blinking, caps lock and
scroll lock and I saw no console at all!
