Well, I've accumulated quite a few changes from the 2.9.5 drivers, so while there may still be some glitches to be worked out, I think it's about time for a new official driver release. The new files are at ftp://hyper.stanford.edu/pub/pcmcia.
Changes from previous releases are at ftp://hyper.stanford.edu/pub/pcmcia/CHANGES.
One fairly major change is that the new drivers will probe for working memory windows on their own. The default window in the packaged config.opts file is now 0xc0000-0xeffff, and the drivers will check this entire region for ranges that seem functional. I would like to hear about how well this works in practice, particularly if you had to specify a non-standard memory window in config.opts for previous driver releases. Try changing your window to 0xc0000-0xeffff and see if the drivers can successfully work things out.
CardBus controller support is hopefully getting better, but still doesn't work properly on some platforms. HP Omnibook 800 models still seem troublesome, for example.
