The software fix is better than the capacitor because it works on all lines to 
the card, not just the clock. With just the capacitor on the clock line the 
other lines may give enough interference to upset the GPS during card access.

That's my translation anyway.

Another question - might the added capacitor on the clock line cause problems 
with the lower drive strength that's now default?
