This is for ubuntu, but might work in linspire
I have a Handspring Visor. To get it working with Feisty, I had to edit the /etc/modules file:
gksudo gedit /etc/modules
add visor on a new line to load support on startup. Use
sudo modprobe visor
to add it temporarily right away.
After that I was able to sync the visor in Feisty.
