SIR is an indication the kernel got seriously stuffed up in trap 
handling code.  And it doesn't look like OBP properly recovered since 
you're not getting to the `ok' prompt.

How far did it get?  Can you capture the kernel output during boot?

Also, try disconnecting the keyboard and using the serial console.

Not getting to the `ok' prompt makes me suspect the video card, but maybe 
OBP just switches to the serial port after an SIR.  

To diagnose the problem we really need to get the pc value of the SIR 
instruction that was executed.
