Bad SD card controller?

[ttz]

Seems everyone else has no problem with the SD card but me. I thought
to upgrade with the latest uboot.  I tried few more images and latest 
images bundle I tried is the following:

- u-boot-gta01bv4-1.2.0+git3e66c078003607a7d1d214c15a5f262bc1b4032f+svn20070829-r2.bin 
- uImage-2.6.22.5-moko11+svnr2937-r3-neo1973.bin
- OpenMoko-scaredycat-openmoko-devel-image-glibc-ipk-P1-Snapshot-20071021-fic-gta01.rootfs.jffs2

doesn't seem to change anything as I still got the mmc I/O error with
the two SD cards come with my Adv set as well as another SD card of my own.
All of the three cards can be read and written with no problem on other
machines(linux and windows). This gets kind frustrating.

I've been trying to search the Wiki to find a support contact from the
Openmoko team(not sure if there is one) but couldn't find any.  Is there
someone from the FIC/Openmoko who I can consult with this problem?  

Thanks!

Tom
