I've spent a considerable amount of time looking through ata/busdma  
drivers, they need a lot of tidying up, lack of comments doesn't help  
either... i'd like to grab the handle on busdma & ata projects, with  
the aim of having them in production state for  6.5-STABLE.

I was also looking at systinstall, which requires a major rework, and  
we have some ideas for that too, I'd say also aim for 6.5. I also am  
going to talk to Scott L. about it in the near future.

If you have any ideas/suggestions for the above drop me an email.

Igor :-)
