No, I just wondered if there's a reason gem(4) wasn't
included in the kernel, f.e. hme(4) worked better for
you or something...

Well, if you can't netboot them you already lost when it
comes to getting a working kernel onto them unless there's
someone onsite who can insert a CD with a working one.
Otherwise you can experiment pretty much anything including
removal of the drivers required to mount root remotely
as long as you've access to the serial console.

That might make the difference and I've planned to give
that configuration a try but I need to fetch mine from
the datacenter in order to do so.
