Well it seems to be working fine, although, i had to change the default (not the application specific) reported version of windows to win2k, and of course completely exit X.
This btw is under the following system configuration:
Kernel version: 2.6.12.6
glibc: 2.3.3
X: Xorg 6.8.1.99 (minimal DRI build from Xorg)
cxoffice: 4.2 pro
msoffice: Office XP Pro SP3.
