Using sdcard for debian may be no problem. What I currently don't know, is
if I still can use uBoot or have to install Qi with seems may fail. I don't
want to
kill the boot manager accidantly and then be unable to reflash :-)

But this is RTFM I must do :-(

BTW, I have a 16GB card that is working - at least seen with navit accessing
the
germany.bin file :-)

Currently I download the new FSO image from today to see if there are no
more
problems with GPS.

What has been failed is upgrading from 4.1 to testing as I then no more have
any
XServer or GUI :-(
