I understand, but I don't have all possible cards, and I depend on what
users are reporting.  In absence of reports, I prefer to work on things
I can actually test.

0156:0002 alone is going to be a big headache.  Basically, you would
need to replace it with textual IDs for all Lucent cards and remove the
numeric ID.

Well, I agree that there are many things in hostap that are not in
orinoco, such as firmware download and WPA.

The later is true for the drivers compiled into the kernel as well.

I agree, that's suboptimal.

I actually hoped that some userspace solution would appear that would
make it unnecessary to handle it in the drive.
