In case this ends up in the FAQ or something:
My description wasn't very clear. In the "regular" memory model, you get
only one 256MB data segment. In the "large" model you get eight 256MB data
segments, the full 2GB address space (the text and stack segments are
still separate, 256MB each). The linker/loader "-bmaxdata" operand selects
the "large" model. The above applies only in the 32-bit case. In the
64-bit case you're apparently always in a "large"-like model, but you're
using 36 bits to select a segment-table entry instead of 4 bits (so the
virtual address space is about 1 trillion TB 8-) and there is no need for
"-bmaxdata".
