I see...

Fabrice, since this change breaks compatibility, is there a way to either:

* Add a parameter to load "old" images with the old bdrv_set_geometry_hint 

or

* Provide a simple script to convert from the old to new format?

One more thing Fabrice, regarding the message about the RTC. Could you
detect if the user is running 2.6.x kernel and if so, avoid showing
the RTC message please?

Thanks,
Hetz
