Subject: [PATCH] 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.
