Subject:    [PATCH] ia64 hpsim: bump RAM size to 2GB

When the ia64 kernel runs on ski it only gets 130MB of RAM,
which is too little for many workloads.  Bump it to 2GB.
Tested with ski-1.3.2 on x86_64.

Maybe this should be runtime configurable, via something like
"ski bootloader --mem=2G vmlinux ...", but that would require
reworking the bootloader's command line parsing code.
