It's going to get worse.
We have to split between the different issues we have seen. Tools issue (the wpa_supplicant problem). -> those can only be fixed by people upgrading. Fortunately, there are not so many tools affected, and new version of those tools were released last April/May. As I said, most distro have those in the pipe. In-Kernel driver issues (the Orinoco driver problem). -> those can be patched and fixed as we go along. I would not worry about those. Out-of-kernel issues (the ipw3945 driver problem). -> those drivers need to be updated. That's the problem of living outside the kernel. Very often those drivers are reactive with respect to kernel API changes, rather than pro-active, so there is not much we can do.

Actually, it's impossible. New userspace can work across both version, old userspace fails on new version.
The whole point of the -rc process is to find problems and the scope of it, there is no way I can know everything. At this point, we can decide if WE-21 should go in 2.6.19 or wait for 2.6.20. But I know that most Linux-Wireless people such as Dan and Jouni have been waiting impatiently for those changes...
Have fun...
