That's what I was trying to say ;-)

I am.

Sounds like a plan. Where can I find a list of the branches in the  
4.0.1 meta data? I'm using the following to select one at the moment:

WRMACHINE_Vortex86DX  = "common_pc" --- I'm guessing I need something  
else here.

SRCREV_machine_pn-linux-wrs_Vortex86DX ?=  
"0431115c9d720fee5bb105f6a7411efb4f851d26"

No, it seems perfectly reasonable to have this in 'common-pc'.
