I am very happy to report that NetBSD 3.0 has been ported to the  
PowerMac G5 and successfully boots into single user mode using the  
built in memory disk.

This is still very much work in progress as a lot of driver support  
is needed including drivers for the SATA controller on the G5, SMP  
support, support for the PMU to control the fans etc. I have added  
support for the U3 north bridge including PCI bus probing and  
configuration.

I am in the process of cleaning up the code and will post the diffs  
shortly. I'd appreciate it if folks could volunteer and help out with  
the driver support.

Thanks,
Sanjay Lal
