thanks for the hint!
but here it looks a little different:
root at neo:~# find /sys/bus/ -name '*sdi*'
/sys/bus/platform/devices/s3c2440-sdi
/sys/bus/platform/drivers/s3c-sdi
/sys/bus/platform/drivers/s3c-sdi/s3c2440-sdi
/sys/bus/sdio
/sys/bus/sdio/drivers/sdio_ar6000

the location is in devices and in drivers I see s3c-sdi

so I can find the unbind here:
root at neo:~# find /sys/bus/ -name '*unbind*'|grep sdi
/sys/bus/platform/drivers/s3c-sdi/unbind
/sys/bus/sdio/drivers/sdio_ar6000/unbind


how I can check if it's in bind or unbind state?
maybe the scripts in qtmoko try to unbind it using a wrong path?
