Nope, this patch doesn't work on either of my sdcards, and have been
reported on avrfreaks as working just sometimes. One of them being the
one that came with the STK1000.

There already :(

I'm hoping that 2.6.23-rc3 changes to MMC has fixed it. But
unfortunally using make menuconfig in buildroot and changing options
at the "Linux Experimental" does nothing at all (at least in AVR32)
