I’ve been using (or, in some cases, trying to use) that when it was brand new. Kernel side was relatively easy - but there was a lot of compiling custom versions of XFree86 trying to get acceleration working properly.

On the one hand a bit sad to see that kind of history I’ve experienced myself go - on the other hand, it’s probably been a decade since I’ve last used something without KMS, and the ease of use of modern KMS drivers is way ahead of all the older stuff.
