Yes, please.

On another note, the hardware pack for Mele a1000 does not seem to work 
for MK802, but the Ubuntu 10.04 image released by Tom works. I'm not 
really sure why and I can't test it because I don't have such hardware 
for now. So If somebody is willing to test it on MK802 and find out 
what's wrong it would be nice. Thanks.
