The problems with r600g are typically related to performance rather than to rendering correctness or stability.
In this case we have 10.04 LTS which results in pretty old stock KMS/DRI2/Mesa. Also keep in mind that not every user out there is rebuilding Mesa with dload support for S3TC decoding and installs accompanying third-party lib. So I still would recommend to give Catalyst a try.
P.S. BTW, Henri, what should Peter do in case he would get perfectly rendered picture with Catalyst driver and bugged render with OSS driver? Whose bug should it be considered - Wine or Mesa?
