That takes address-space also. If you look at the boot log, you will probably find that there is a lot of "reserved" address-space. Since RAM needs to "share" such address-space, any RAM behind the reserved addresses will not be accessed. Cheers, Dick Johnson Penguin : Linux version 2.6.13.4 on an i686 machine (5589.55 BogoMips).
