It seems the physmem option in /etc/system and as given to the kernel boot is broken. Booting a system with physmem set to something lower than its actual size fails to give any message, and the system has its full amount of memory available. Same applies to using kernel options (-B physmem=xxx). The latter shows a warning in the kernel log that memory has been limited, but tools like 'top' show the full amount of memory. I fist saw this on OI148, but later checked if the issue was reproducable in S11ex, which it was.
