this one seems to be working w/ a standard sed :

==========----------========== CUT HERE ==========----------==========
#!/usr/bin/sed -f

# since ata[0-9] requires ata alone, delete them.
/^#*[ \t]*device[ \t]\{1,\}ata[0-9]\{1,\}/d

# delete fd[0-9] and fd alone.
/^#*[ \t]*device[ \t]\{1,\}fd[0-9]\{1,\}/d
/^#*[ \t]*device[ \t]\{1,\}fd$/d

# get rid of terminal spaces
s/[ \t]\{1,\}$//

# hints stuffs
/^ident[ \t]\{1,\}/ {
        s/^ident\([ \t]\{1,\}\)\([a-zA-Z0-9_]\{1,\}\)/hints\1"\2.hints"/
#                                 ^^^^^^^^^^ I'm not sure about this
#       are underscore and digits valid characters here ?
s/^\(#*[ \t]*\)pseudo-device\([ \t]\{1,\}\)/\1device\2/
s/^\(#*[ \t]*\)device\([ \t]\{1,\}\)\([a-zA-Z_]\{1,\}\)\([0-9]\{1,\}\)\([ 
#                                      ^^^^^^^ also, here ?

\t need to be replaced w/ real tabs (under vi, :%s/\\t/<TAB>/g)
just in case, I put them here to be reliable (and visible :) via email.
