Yes, I understand.  I've been looking at the XFree86 version of the 
driver already.  Unfortunately any time I spend on this will have to 
apply to Windows guests as well, as you can imagine.  My company sells 
Windows-on-Linux software that uses QEMU, so it has to play with Windows 
guests ;)  In fact, there was a recent PS/2 mouse patch on this list and 
a hack for XFree86 which was very simple.  I didn't try it, but if you 
are using Linux guests you can probably get absolute positioning very 
easily.  I don't recall who posted the patch - it was recent.  The fix 
for the guest X server is very simple as well.

Yes, given the state of USB in QEMU it's probably best to stick to 
serial for now if you want something that works very reliably and soon. 
  Serial would be my intention.  The only issue may be how this plays 
with Windows guests - again, this is very important to me.

Thanks!

I would think so too.  But, in looking at the XFree86 version of the 
driver, it's apparently configurable and my fear is that Windows will 
flick it to relative mode so it can play acceleration tricks.  But 
anyway, it's worth investigating.

Actually Jim C. Brown just posted a note that there is an existing 
patch, but I can't seem to find it.  Jim, I'd be glad to look at it even 
though you are saying that it is still flaky - perhaps it can be fixed.

Thanks,
