By "don't work" what exactly do you mean? Do you still see the
greenish background of the show-paren face on the line numbers? Or do
you see something else?

That's a different issue, but I think it, too, can be solved, see
below.
(Btw, I wonder why you use a black foreground for this face if your
background is also black. What am I missing here?)

That's strange: are you saying that a 16-color xterm doesn't have
"black" among the colors it supports? I don't think I've ever seen
that; perhaps the settings for xterm on your system deliberately
define "black" as something whose RGB value is not #000000?

What happens if you specify the 'linum' face to inherit the background
from your 'default' face, like this:
(custom-set-faces
'(linum ((t (:inherit default :foreground "black" :weight bold)))))
Does this produce good results?
