[Bug 607906] Re: 2.6.35-devel is unable to mount root on mmc

[Robert Nelson]

Yeah, my XM Rev A (256Mb) has the same issue.  Although i haven't looked
at it closely in awhile, is there any kind of "Write Protect" level on
the mini-sd card holder?  I don't think there is, well the kernel still
thinks there is, we will have to add another check here for the XM, to
ignore the gpio_wg...

Something like???
