Indeed, your patches work, thanks. Boot log follows down below.

The current kernel is not very well tuned for OMAP 2420 since it takes 
2 minutes and 44 seconds to boot it to the "Enter pathname of shell..."
point. In comparison our kernel branch takes 19 seconds. Userspace was the 
same yesterdays current on both.

Hopefully we can post our changes soon, since the biggest road
block is now fixed. If anyone has suggestions how to improve patch
flow from interested parties like us towards NetBSD, we'd very much like
to hear them.

Thanks again, Matt.
