I solved this in modprobe.conf:
options sdhci debug_quirks=1
If I uderstood the source, that touches the controller clock on each reset for
the operation to work.
2.6.28-rc2 still doesn't see the card without that option.
And there is another problem, -rc2 doesn't reboot on the One, but that's for
another thread (don't know if it can be related).
