If you pass mem= you have to pass mem=3840M. Yes, it sucks, but if you genuinely have a machine which is so fucked up that you can't rely on the memory map the BIOS presents to you, you have problems to begin with.
Oh yes, this is why GRUB passing the mem= parameter gratuitously was beyond total and complete brainfuckage.
