The serial driver worked fine for me about a month or more ago. Then
there was a large update with the latest 2.5.x bits and it's very
possible that the driver got broken. There are other Au1x problems in
2.5 as well. The 36 bit address patch is not there yet. The last time I
played with 2.5 the kernel mounted the root fs and then hung trying to
start a userland process ... and I haven't had any time since then.  I
think you're in new territory here but, hey, someone needs to clean up
everything :)
