I took a look at these patches, and they are certainly something we'd
consider for a point release of the existing Debian release if they
can be backported to the 2.6.18 base in such a way that the changes
will only affect new hardware - since they are mostly just adding ids,
etc, that might be the case.

Do you know of any reason these changes wouldn't work on a 2.6.18
base? Would you be able to run QA on one of our daily builds if I
pointed you to snapshot debs with these changes?

The combined mode patch for sb700 depends on a quirk that was added
for sb600 after 2.6.18. I could of course backport this quirk only for
sb700, but is there a good reason for adding it for sb600 as well?
