Sorry. I didn't finish my thought here. (I *did not* mean "So?" :)

So... yes, we should make sure its not broken. Could you explain some
more details about the different interrupts fro the driver? If the two
interrupt types come from different sources, is there a problem actually
using the alarm irq to emulate the update irq? In other words, can we
just skip the update irq management code? Or is there a draw back to
that?

thanks
