Well. Now I am quite surprised. I did the following... obtained an image
of the same chip, formatted by the camera, both under 2.6.23 and
2.6.24-rc1 [1], after umounting the volume, and:

Uf. So I reformatted (under 2.6.23) the partition p1, and now the card
works both under 2.6.23 and 2.6.24 (although now it's not detected as a
photo card, but I suppose that's normal). But again...

Shouldn't they be equal? I have no camera handy now, I will try again.
If it's of some interested, I've put the images on line on 

http://www.dea.icai.upcomillas.es/romano/linux/info/lk2624-rc1-mmc2/


I tried to loop mount them, but I forgot how can I mount a partition of
a loop device... I have loop0 but not loop0p1... there where a "seek"
magic but I cannot find it now.
