The source of your problems is that there are two sets of modules named
orinoco.o and hermes.o. Check under /lib/modules/2.4.20... You'll find
that one resides under pcmcia, the other kernel/drivers/net/wireless.
Unfortunately, modprobe is loading the wrong set of modules.

Same version numbers (0.11b = 0.11b): Success

Different version numbers (0.13b != 0.11b): Failure
The orinoco_cs module is version 0.11b, whereas the orinoco module is
version 0.13b. Obviously, the kernel orinoco driver is being loaded
instead of the driver from pcmcia-cs.
The 2.4.20 kernel source (in the kernel-source package) has version
0.11b (I think that 2.4.18 also has this version), which is why this
problem doesn't appear more frequently. What patches did you apply to
this kernel? Where did the newer driver come from?
One way to fix this would be to use insmod to explicitly load the
correct drivers, or to delete the orinoco and hermes drivers under the
kernel subdirectory and run depmod. The real problem is that there
should not be two modules with the same name.
