 First off, this seems to only happen with my 16GB FAT32 formatted SDHC
 card (however, it could very well be with all cards, as I have not tested
 with others besides a very quick "yes, it works"...I should probably test
 more with others).  However, it seems that the card will work at rare
 times, so I may have just gotten lucky with the other card I tried.  I
 have verified the card works perfectly attached to the XO through a USB
 card reader.  Once, after a round of testing, Windows (I was at work..)
 saw the card as unformatted and wanted to reformat. I would normally think
 it was a bad card at this point, but as it works perfectly in a different
 reader...  Unfortunately, I have been very busy lately and not had time to
 go further with more debugging.  Let me know if you have some ideas, or if
 I am being stupid about something.  ;)   Here are the relevant bits from
 dmesg:
