That worked :-)

However, I found another (smaller) card where it didn't help :-(

The complaint appears to be valid, given fdisk's output .. is this
something to do with the 'relative address'?

imb_at_toshi:/usr/src> fdisk /dev/mmcsd0
******* Working on device /dev/mmcsd0 *******
parameters extracted from in-core disklabel are:

parameters to be used for BIOS calculations are:

Media sector size is 512
