fusion0.7 + vxWorks skin + sample

[Marco Cavallini]

> You don't need rtai_vxworks.ko in UVM context. When used this way, the

# insmod rtai_hal.ko
RTAI: Intel chipset found and SMI workaround not enabled,
      you may encounter high interrupt latencies.
Adeos: Domain RTAI registered.
RTAI: hal/x86 loaded.

# insmod rtai_nucleus.ko
Adeos: Domain IShield registered.
RTAI: fusion core v0.7.5 (Echo) started.
