One big difference between Your old system and newer one is software
emulation of VM86 (in DOSEMU) on 64 bit machine, including CPU emulation.
Problem may be in this emulation implementation, see DOSEMU source code
under src/emu-i386/simx86 - it seems as some sort of jump problem.
You may also tried compile DOSEMU from SVN, which is including several
patches from virgin 1.4.0, and/or debugging it.
