+Subject: vgabios: Attempt to detect old x86emu and force a fault.
+Upstream-Commit: 8032b8a0fec550de5cb2f7d37aa031cebc2200c3
+Bug-Debian: http://bugs.debian.org/737142
+
+Check for cases where the leal instruction does not work.  This
+instruction is known to not be emulated properly on old versions of
+x86emu.  If a broken version of x86emu is found, force a fault that
+x86emu will easily detect.  This should help prevent soft failures
+when running old software.
