Generally speaking, downgrades are unsupported in Debian (the usual warning is what if the upgrade changed a configuration file format; the old package might be unusable as a result). Bearing that in mind you have a number of options. Ideally, your first option is to try and find an updated driver for your card. Does the free ATI driver support your card [1]? If not, does the packaged proprietary driver support your card [2]? If either of these support your card, you'll find life much easier to switch to them - see the wiki pages for details. If that doesn't work, you'll probably have to use snapshot.debian.org to get the old package version. Basically, work out the date when things worked and then look at [3] for details of how to use the archive.
