the struct 'openrd_ge01_data' is wrapped in 
#ifdef CONFIG_MACH_OPENRD_CLIENT too and only exists if you want the 
board support for it.  So although machine_is_openrd_client() will 
exist, the compiler will barf that openrd_ge01_data does not exist; the 
alternative is to have it grumble (when you do not want the Client 
support) that there is an un-used struct floating about.

I was under the impression the latter is considered worse than the 
former, I personally am not bothered either way.

I knew someone was going to say that :)  Will do though, so 'watch this 
space'.

Cheers
