Yes, that was my suspicion. :-)  Not unreasonable really as it 
shouldn't be hard to work out a quirks list for any given device, but 
I'd rather keep the same method of device identification across both 
config files.
By the way, your email didn't contain attachments but had a humungous 
blob of patch appended instead. Could you resend (all in one email is 
fine, but separate attachments) and remind me of the order in which to 
apply them? Thanks!
