fsfe smartcard help

[Remy van Elst]

Good Evening,

Today I've received my fsfe smartcard and I've set it up at my work under 
arch linux with the following guide: 
http://wiki.fsfe.org/Card_howtos/Card_with_subkeys_using_backups. 
Now I am at home, using ubuntu 10.04 and I would like to be able to sign my 
mail using my fsfe card. (I use cone). 

I've tried to follow the guide again using the backups of my 
secring/pubring. While my key gets imported it does not ask for my 
smartcard pin, but for my secret key passphrase. (Smartcardreader in my Dell 
keyboard). The contents of the card can be read with gpg --card-edit. 

remy at janedoe:~$ gpg --help
gpg (GnuPG) 1.4.10

remy at janedoe:~$ gpg --card-edit

gpg: detected reader `Dell smart card reader keyboard 00 00'
General key info..:

Is there a way that I can use the card on other PC's then the one I;ve set 
it up? 

Sincerely,
