Can you explain why we shouldn't use this other than for win2k install?  
I'm not too familiar with the IDE emulation and am not sure what the 
consequences would be.  Of course, it is easy to disable at run time by 
just setting s->ide_set_irq_from_timer = 0.  I am just trying to 
understand more about this - what the real problem seems to be, what the 
danger of using this hack after install is, etc.

I will investigate your AIO solution as well - do you feel that it is 
more correct than this non-AIO patch?
