Sorry, this is wrong, actually the ubuntu 13.04 (and only the 13.04) is using
the nvidia proprietary driver, not the nouveau.

One more test that works:

 - hardware 1: Ubuntu 13.10 with nouveau (from ubuntu 13.10 repository) and 
offboard geforce 7200GS Chipset: G72 (NV46) , Family : NV40

The problem is only with geforce 8500GT Chipset: G86 (NV86) , Family : NV50
And this same board works fine in ubuntu 11.10 with kernel 3.0 and nouveau from
11.10 repos.

So there's some regression between kernel 3.0 and 3.11 (tested w/ 3.12 too)
and/or nouveau versions between ubuntu 11.10 and ubuntu 13.10 with this
specific geforce 8500GT Chipset: G86 (NV86) , Family : NV50 when try to work
the YUV overlay scaling in mame
