Somebody in the thread at some point said:

| [    3.165000] mmcblk0: mmc0:b368 SMI   498176KiB

That's the good part above, it talked to the card and got information
out of it (512MB card).

| [    3.170000]  mmcblk0:<6>glamo-mci glamo-mci.0:
| Error after cmd: 0x302

Then it all went wrong, 0x0302 is actually CRC error with data ready,
never seen it before.  After that it's dead meat.

Looks like bulk transfer on that card doesn't work under current default
conditions, eg max clock speed.

You can meddle with max clock speed on kernel commandline, try eg

glamo_mci.sd_max_clk=10000000
