Well, that's interesting.  It seems that both the kernel looks at 
OSLoadPartition from the prom when being loaded via arcboot.  Arcboot 
uses OSLoadPartition to determine where the kernel and arcboot.conf are 
stored, and it uses the SGI naming scheme to do so (eg the 
pci(0)scsi(0)disk(1)rdisk(0)partition(X) bit).  The kernel uses 
OSLoadPartition to determine the root device, and apparently the 
append="root=/dev/sda3" from arcboot.conf isn't getting passed, or is 
being overridden.  Try changing OSLoadPartition to /dev/sda3 from the 
prom.  Arcboot will spit an error that you should change it to something 
else, but then will scan the other partitions for /etc/arcboot.conf and 
should auto-detect what partition it really needs and then boot normally.
