"/dev/mds*" is not  a  common  name  for  Linux.  I  guess  you  mean
/dev/mtd* instead?

Yes, if the kernel is not configured to include MTD support then  you
will   have  to  reconfigure  it  and  build  it  (or  at  least  the
corresponding  modules).  But  that's   a   trivial   task,   nothing
"dramatic".

I believe you find life such a problem because you  think  there  are
the  good  people  and the bad people. You're wrong, of course. There
are, always and only, the bad people, but some of them are  on  oppo-
site sides.                      - Terry Pratchett, _Guards! Guards!_
