well from what Andy says they have  found a software fix which
- keeps good SD card perf (for cards tested so far)
- doesn't degrade gps signal

the software fix will be in the new kernel very soon and
- switches off SD clock when not needed
- reduces the drive strength of the SD signal when on

so looks to me that the hardware kids can go ahead if they want to....
but not proved necessary right now...
