After booting the machine with this patch, it works like a charm,
looks fairly stable, Myrinet 10GE card up and running. So I
wonder: would it be possible to include this realbtx into 7.0-RELEASE?
It seems rather important, as many machines are now being
installed off USB CD drives and USB keys...

Thanks a lot,
