ok, I've built and booted linux 2.5.70 to 2.5.75, and it seems that the
detecting the aironet card as a memory_cs device happens in 2.5.74

_but_ I did come across a number of other weirdnesses on the way.
1. 2.5.71 was missing a #include <linux/cpu.h> in flow.c
2. when i patched 2.5.70 to 2.5.71 and then 2.5.72 somehow SMP became
enabled, and this stopped pcmcia from working at all
3. my /etc/defaults/pcmcia contained the line PCIC-i82365, which seemed
not tp cause 2.5.70 any problems, but after that i had to change that to
yenta before pcmicia started successfully

I assume the next step is to apply the 2.5.74 patch in pieces ?

cheers
Sven
