Hi,
First of all let me say that I can hardly wait antiX-12 to be released (the new metro ui and stuff.. [not] __{{emoticon}}__ )
Seriously, I think it will be very good, I've already tried rc2.
I have, however, some problem with my VGA. This (not so) old HD4890 is no longer supported by AMD (#*%^Đ$!!!), and their last good proprietary driver (12-4) doesn't work with Xorg 1.12 (or 1.11). So I will have to fall back to 1.10.
I'd like to know the best way to do this.

Actually I have already done this in my every-day-used antiX-M11 after an accidental upgrade of xorg, but I'm not quite sure that this is the very best solution. Here is what I did:

Added this line to sources.list, and commented out everything else:
deb
========= SCRAPER REMOVED AN EMBEDDED LINK HERE ===========
url was:"http://backports.debian.org/debian-backports"
linktext was:"http://backports.debian.org/debian-backports"
====================================
squeeze-backports main contrib non-free

Added this section to etc/apt/preferences, this way I downgraded and"held back" these packages:
Package: xserver-xorg xserver-common xserver-xorg-* xserver-xorg-input-* xserver-xorg-video-*
Pin: release n=squeeze-backports
Pin-Priority: 1001

Reinstalled these packages, now the older versions.
Reenabled the original repos
Finally I was able to install the amd 12-4 driver with sgfxi -o 12-4

(Sorry for being Captain Obvious)
I'd really like to know if there's a cleaner, simplier way; maybe there are other open source drivers that I don't know and work well with games and xbmc; or which exact packages I should hold back... or anything else.

Thanks in advance, this is not urgent at all, good work with the final touches on antiX-12!
