Hang executing memtest86 from Livecd

[roger]

Loading memtest86 from a livecd hangs on memtest86 execution.

Thought the following was just an issue with running qemu with
"-no-graphic" option.  But running without "-no-graphic", I still get a
hang with executing memtest86.

$ ~/tmp/qemu/bin/qemu -L ~  -nographic -cdrom /dev/hdc
