@cinnagingercat: Okay, basically, everything works as usual, except no SSH on diags :?.
Stupid question: In this case, why not use the jailbreak
(the usual long method, for FW 4.1), and then the usbnet
EDITē: Which I'd probably have to repack (usbnet package) to handle the new K4 device code, but, heh, still.
EDIT^3: The packages have been repacked. They should appear/install/work on the new K4 now
