Merge zeep.pool:/z/saidi/work/m5.head

into  zeep.pool:/z/saidi/work/m5.nm_m5_pull

SConscript:
    dram memory needs to be converted to newmem before we can use it
dev/ide_ctrl.cc:
    don't need this printing in newmem
dev/ide_disk.cc:
    will read stats in next commit
dev/sinic.cc:
    merge sinic from head, still needs work
