the last I checked Avi told me that Win98SE did some stuff in real mode which kvm can't catch,
I believe that depends on the vendor:
According to the [Intel] VT-x spec, guest OSes cannot operate in real mode… AMD SVM, on the other hand, supports real-mode for guests… – http://lwn.net/Articles/182080/
(The article is about Xen and predates KVM, but the hardware is the same.)
