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,\}/ {
h
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 ?
H
x
}
s/^\(#*[ \t]*\)pseudo-device\([ \t]\{1,\}\)/\1device\2/
s/^\(#*[ \t]*\)device\([ \t]\{1,\}\)\([a-zA-Z_]\{1,\}\)\([0-9]\{1,\}\)\([
\t]*\)\([^#]*\)\(.*\)$/\1device\2\3\5\7/
# ^^^^^^^ also, here ?
==========----------========== CUT 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.
