Hello all,

I sent this to Julien Cristau originally, but as I got no response I'm  
sending it to the list in case someone else has an idea (or in case it  
just got caught in Julien's spam filter the first time).  Obviously it  
is something I would like to solve before the 1.8 release if at all

> Hello,

> the VirtualBox Guest Additions mouse driver work with those systems  
> (as virtual systems obviously), and am blocked on the fact that

> mouse driver there is no such device, as the driver talks to our  
> "VirtualBox" PCI device to get mouse information from the host.
> I was wondering if you had any suggestions as to how to make this

> Thanks in advance!
