A few things I've discovered lately:

1. Capn Voyager:
I just discovered that another navigation program, Capn Voyager, installs under Wine (running Linux Ubuntu) on the XO without any problems. I haven't tried connecting a GPS yet but as far as loading and viewing charts it works fine. The version I have is 6.1.0 and it doesn't have AIS support. All I did was put the Setup.Exe, Copy_SoftChart.exe and CAPN.ICO on a USB stick and issued:
wine /media/disk/Download/Setup.Exe
You can then copy your charts into: ~/.wine/drive_c/Maps


2. Making a backup copy of your SD card that has Ubuntu on it:
I found that all 8GB SD cards are NOT the same size and in order to copy from your existing SD to a backup one, the backup has to be the same size or larger. That may seem obvious but since my SD card was only half full I thought it might be able to copy to a smaller one. So if you may want to order two SD cards of the same kind/size if you are just installing Ubuntu. The command is:
dd if=/dev/xxxxxx of=/dev/yyyyy conv=NOERROR,NOTRUNC
The xxxxx is the original you are copying from and the yyyyy is the one you are copying to. A df command will show you what they should be probably something like mmcblk0p1 and sda1.
You can do this under Sugar and make sure you put the lock on the xxxxx SD card so you don't accidently reverse them and destroy the original.
