Distros and kernels that support EVMS are becoming scarce.  Sadly, it's the
death spiral of EVMS.

The last I looked, SystemRescueCd (http://www.sysresccd.org/Main_Page)
supported EVMS.  Not sure about BBR, though.  IIRC there's a kernel module,
dm_bbr, that you have to build and insert in order to use BBR?

I don't think there's any way to read those drives except by EVMS+BBR.
However, I don't see any reason that you shouldn't be able to build a
kernel to do that, as long as you have the EVMS packages.  They're gone
from the Debian archives now, but are still available-- let us know if you
need them.
