No, isn't.  Running vanilla 2.6.37-rc5 now, seeing both success and 
failure with the very same kernel.

The driver is compiled statically into the kernel now.  Booting with the 
device plugged works, it seems to initialize the device largely 
sucessfully, although some errors are sprinkled in.  The firmware one is 
probably just a matter of making sure the firmware is in the initramfs, 
didn't look at that yet.

Trying to fix the firmware issue by just unplugging and re-plugging the 
device once the system is fully  up'n'running (and thus /lib/firmware 
available) results in a failure which looks pretty much like the 
original report.

Any idea?  Initialization order issue?  Timing issue?

cheers,
