Jens,
Here are some more Sysace patches based on comments received on the
first series and a run through sparse. Can you please queue them up
for 2.6.24?
Thanks,
g.

The previous patch to move the interrupt handler registration moved it
below enabling interrupts which could be a problem if the device is on
a shared interrupt line. This patch fixes the order.
