(Sorry about late answer, but I haven't had time to experiment with
this until now)
I've tried installing the Orinoco drivers 0.13a (I suppose it is
these: http://ozlabs.org/people/dgibson/dldwd/). I don't know if I did
anything wrong but what I did was just make/make install in the
orinoco-0.13a directory. (I had a kernel source tree that was built
and installed.) I had this same problem, when I started up the
computer, the transfer speed was still 10kB/s, and when I pulled out
the card and reinserted it again, the system stopped responding
(hanged).
Should the modules be deselected in the "make menuconfig" before the
orinoco 0.13 is built? Does pcmcia-cs (this is the userland tools, no
drivers, right?) need to be patched too? I use the Debian package of
pcmcia-cs.
I've also tried using 2.4.17 (without the orinoco drivers 0.13) but it
works just like 2.4.20: Every time the system has started up, and only
then, I have to remove the card and put it in again to make the
transfer speed normal. I don't think the problem appears again when
running, I just have to do this once.
I haven't tried with 2.5.* yet. Had some trouble compiling it last
time I tried.
