Thread-digging i know, but I thought I should put out a massive thank you to all whom contributed to this thread, as my kobo is functional once more after an incident involving calibre & my clumsiness effectively nuked the database and every book on my kobo. Following instructions & downloading files listed here revived it once more and got it fully functional again.

For anyone reading through this far after finding themselves in a similar situation, make sure you follow the instructions and that you use mkfs.ext3 with the -j argument on the SD card, and not automatically assume that just using mkfs will do the right job. I am not totally sure of why, but it was that one difference that got the flash card readable by my kobo upon re-install, and thusly my kobo working again.
