i can not use the onaips.blogspot.com version because my device is not rooted. 
can't your correction be backported to this version that do not rely on any 
.apk or root access ?
could you publish your correction as a patch that could be applied to this 
version ?
thx.

As far as i know you need to have your phone rooted, in this version also... 
I'm using a similar aproach to access the framebuffer as this, so there are no 
big differences...

my htc legend is not rooted and i have been able to connect the viewer to the 
server and produce the screenshot above, i believe it proves that access to all 
needed ressources was granted, am i wrong ?

I see what looks like the same issue with Android on TI BeagleBoard.  I don't 
have root or busy box working, but the VNC server does still work.  My problem 
is similar with a green garbled screen and no ability to click-through.  

Would changing a few compiler parameters create a new binary that works?

Try using this attached androidvncserver binary instead.  It is from the data 
in the android app and does not require busybox or rooting.  It fixed the issue 
for me.

Same issue as http://code.google.com/p/android-vnc-server/issues/detail?id=23. 
This might be the cause:

http://code.google.com/p/android-vnc-server/source/browse/trunk/fbvncserver.c

Line 191:   /* TODO: This assumes scrinfo.bits_per_pixel is 16. */
Line 192:   vncscr = rfbGetScreen(&argc, argv, scrinfo.xres, scrinfo.yres, 5, 
2, 2);

As you can see the screen is always initialized for 16-bit color depth. All 
devices that do not work use 32-bit depth.

Too bad this project seems to be abandoned and not maintained any more...
