  It works fine for me! (RiscBSD 1.2 though, maybe a difference)

  As to StrongARM.  

Will we require a new bootloader as well as a new kernel?

I tried (just for the hell of it) booting the latest kernel with my SA 
fitted, and as soon as I pressed boot, it gave an error (abort on 
somethingorother) but !BtRiscBSD didn't die, and RiscOS stayed working 
fine. Presumably this is happening in the early stages of loading the 
kernel, before it even starts running it?  (This is using the latest 
bootloader from the 1.2-beta directory)

  Just wondering!

Ale. (Who is now going to go back to RiscOS just to watch those MPEGs again!)
