I just reconfirmed that
d6a2914984c89fa0a3125b9842e0cbf68de79a3d~1 + 
88c73d16ad1b6c22a2ab082064d0d521f756296a works,
while
d6a2914984c89fa0a3125b9842e0cbf68de79a3d + 
88c73d16ad1b6c22a2ab082064d0d521f756296a bugchecks.

a5af12871fd4601c44f08d9e49131e9ca13ef102 that you tested is after 
d6a2914984c89fa0a3125b9842e0cbf68de79a3d which broke Windows 9x, that's why 
you're seeing it broken.

It also has been a long time that Windows 9x doesn't work with -enable-kvm. 
Maybe even always...
