Yes, it is possible to provide specific parameters to a builder, so it
should be easy to do this.  About the new board file, I understand that
it is just a workaround due to the limitations you mentioned below, and
as such it is not going to be put upstream, right?  We'd also have to
provide a specific parameter to this builder if we want it to use this
board file.

It's been a while since I want to have an ARM buildslave on the
BuildBot, so even with these limitations I still think it's a nice thing
to have.

Thanks for working on this.  I'll have to write special code for this
buildslave, so let me know when you have everything ready.

Cheers,
