Orinoco testing + ARM (Byte-alignment problems, it seems)

Hi, Ben!

The orinoco driver works on ARM just fine.

Not for me.

I'm getting this on ARM only with one particular card with Intersil
firmware (ZCOMAX AirRunner/XI-300) and only once, when the card is
inserted.  I haven't seen this message on i386, but I cannot test that
card on i386 - it has a compact flash connector that's too thick for the
PCMCIA adaptor.

Since the problem with the driver seems to show up differently, it's more 
likely to be a race than an alignment problem.

However, I've just discovered that "cardctl config" doesn't work on ARM
because of the alignment issues (sizeof(config_info_t) is different in
kernel and user space, which makes DS_GET_CONFIGURATION_INFO different).

I don't think it's related, it's just an demonstration that the alignment
issues are not all fixed.  But they don't disappear between boots.
