i'm using Qemu 0.9.1 on Solaris 10 64bit (0805 edition) SPARC, qemu 32 bit 
compiled. It works well, but tap networking initiates tapX interface in 
a strange way (device is running, but has not UP flag and cannot be brought 
up using ifconfig). For TAP i'm using latest driver from whiteboard.ne.jp.
        I have modified vl.c code (exactly the same part of code is in 
net.c in current svn version) in function tap_alloc so it is reduced only 
to opening /dev/tap and allocating new PPA. After it i use "ifconfig tapX 
plumb", "ifconfig tapX ip netmask up" and all works well. See attached 
patch - maybe will be useful for somebody.
                                With best regards,
                                        Pavel Dufek, Czech Republic.
