"The other difference with the hugemem kernel is that the kernel and
userspace address spaces are split 4GB/4GB, meaning that with the
hugemem kernel, a userspace program has access to its 4GB."

The problem is that Roberto's hardware (motherboard + BIOS) does not
remap the memory area used by I/O, which must be inside the 4GB on 32bit
systems, beyond the 4GB barrier. A kernel with the 4G/4G patch would not
change that.
