Hello Gents,

So by following your advices I could get my function called. I had no 
time to retrieve the current
sources patch from the development board, but basically I've pretty much 
got same settings and
status as the legacy BIOS does.

Unfortunately, I still cannot get a VGA output. I start to get coherent 
graphic output as soon Linux
loads the driver, but not before that.

Would you guys have a few additional pointers I could check?

Thank you

Arnaud
