Rev 1.132 was backed out because of the following from BDE:
By returning garbage for the unused high bits of segment registers, we avoid wasting time initializing the bits if the results are assigned to 32-bit variables. movl instead of movw was also intentional, to prevent gas adding pessimal pessimal segment overrides. See src-committers Message-ID: <20030419173421.N15436@gamplex.bde.org>, for more details and how to optimize this farther.
