But I was wrong!
The card does work and it is detected in a standard hentges install.
But, I wanted to remove all the software that I do not use. I have no wireless network, no bluetooth, no need for infrared, so I removed loads of stuff including kernel modules, now the CF card is not detected.
When I try to mount from the command line it reports that /dev/hda1 is not a valid block device.
Any thoughts about the module/software that I should reinstall.
Sorry coredump for breaking your fabulous work.
