I remember somebody wrote dyntick patch...but not sure if it is
already merged into qemu CVS.

Maybe you need similar trick like win98 to halt CPU when not doing anything?

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this is weird.... can you dump
the generated opcode? pls see qemu-doc/tech for more detail on how to
do it.

Before I forgot, do you use kqemu? if yes, do you full virtualization mode?

very weird....do you use precompiled qemu binary? or do you compile by
yourself? if it is compiled by yourself, what gcc version do you use?
