Thanks, and I could test it myself (without any actual card, but at least 
I could see the failure to even set up the bridge, and the fix). 

So I committed it.

When we did the original commit that caused this, we had considered having 
a separate "alignment" value, but I had discarded it because I didn't 
think there was any actual hardware that could even use it. But this 
cardbus thing shows that I was wrong - the two bits may have been clever, 
and it works no worse than the old setup (and slightly better), but I 
think the separate alignment field would probably have been better.

Anyway, it's probably not worth worrying about now. It's not like we've 
ever _needed_ the finer-granularity alignment, so I think we're ok with 
the current setup, but if we ever decide to add the alignment field after 
all, somebody should remind me/Ink about the cardbus thing.
