i can easily reproduce it on panda, while it works as expected on xm:

flag@omap:~$ uname -a
Linux omap 3.0.0-11-omap #18 Mon Sep 19 14:55:51 CEST 2011 armv7l armv7l armv7l 
GNU/Linux
flag@omap:~$ dmesg | grep mmc
[    4.408660] mmc0: host does not support reading read-only switch. assuming 
write-enable.

[    4.454132]  mmcblk0: p1 p2

remove the micro sd card:

[  198.081451] mmc0: card e624 removed

reinsert it:

so it seems a regression in omap4 at this point.
