WoW on an IBM R50e

Quick question to all you hardware gurus out there.
Will WoW run on an IBM R50e?

Specs are:
CPU: Celeron M 1.5
RAM: 256MB Ram (yeah, I know this will need to be upgraded - crucial.com
will get a call).
GFX: 6464MB shared Intel 82855 GME graphicsMB shared Intel 82855 GME.
This is the bit that worries me. I dont know if this is a dx9 solution,
and I doubt very much that it has hardware T&L.

I've been told that adding the -opengl switch will probably alleviate the
T&L issue... What do you think?
Has anyone run WoW on this kind of gfx card (ok, that's maybe too strong a
word for the integrated gfx on the IBM ;o) ).
if so, was it playable?

Cheers
