Doesn't seem so. I applied this patch and it works like a charm just
like before on PB1176. (PL061 is compiled in, so it's not that other
weird stuff being used.)

I hope I'm doing the right thing, boot with card inserted, this appears
in the bootlog:

mmc0: new SD card at address 80ca
mmcblk0: mmc0:80ca SU512 483 MiB
 mmcblk0: p1

Remove card:
mmc0: card 80ca removed

Insert card:
mmc0: new SD card at address 80ca
mmcblk0: mmc0:80ca SU512 483 MiB
 mmcblk0: p1

And so on.

Yours,
