Pretty cool !

I'll implement the few missing bits in layer 1 to properly support
those tonight. (just rita pll config missing).


The patch seems to have a few typo/debug stuff that slipped:

 * 399 referenced sometime instead of 299
 * a "+// JOLLY" debug marker inserted around line 143
 * LOGP replaced by printf at line 289


Cheers,
