    Ok after some further research I figured this out. My last working
    version of the Linux Kernel was 2.6.7 which worked with my rescue
    system. I now applied the bk* patches upwards to check which one caused
    the issue and I figured that this happened between bk3 to bk4 (so the
    problem occoured with the bk4 patch). The diskimage was created with
    mtools 3.9.9 and worked perfectly before.

    export MTOOLSRC=".mtools.conf"
    echo "drive a: file=\"/tmp/bootflop.img\" mformat_only" > .mtools.conf
    dd if=/dev/zero of=/tmp/bootflop.img count=5760 bs=512
    mformat -t 80 -h 2 -s 36 A:
    rm .mtools.conf

    The diskimage was created that way for countless months without any
    problems. You find the image as attachment. After bunzip'ing it you
    receive a 2,88 mb file (don't worry about the tiny size now) with the
    md5sum: dc27cfe332cf96238e80d148c9955b9e
