I was also interested in the gluconeogenesis - gycogen question, so I looked it up:

It took some looking. The biochem texts I found were impenetrable by li'l ol' me. So, no you can't make glycogen by means other than eating more carbs that your body needs for current activities. There's no other pathway.
And what should be of even more interest to the low-carb folks: gluconeogenesis only converts protein to glucose. Fat cannot be converted to glucose. Therefore your protein intake needs to be sufficient to handle your blood glucose needs or you'll burn muscle for it.
