Not 100% sure what you're asking, but I think the answer is 'YES'.
All you need with this DOSOnChip module is a serial connection, whether it's sync- or async, doesn't matter. Set the options and go.
I tried one out awhile back on a '628A for grins. All I did was dump files on a 1GB SD card to an LCD sequentially. Absolutely no use for the project other than to watch characters scroll by really fast. It worked well. A bit expensive, but it takes a lot of the legwork out of a project requiring mass storage.
I was going to use it for datalogging on my OBD hookup. Decided against it and went with the larger Dataflash chips and a USB port instead (thanks alot Mr.E, a lot of sleep lost).

EDIT: Disregard - I missed the point about the AVR-DOS...never mind...I see what you were getting at...
