I did some tests with the new settings. My observations are based on the 
signal strength output in AGPS-UI.

sd_idleclk=1 and sd_drive=2:
The strength of the gps-signal rapidly goes down, then I loose the fix 
on my window.

sd_idleclk=1 and sd_drive=0:
I can't see a weakening of the gps-signal. Signal strength seems as good 
as with sd_idleclk=0.
I copied some (big) files to and from the card, none were corrupted, all 
md5-sums were identical. I'm using a sandisk 4GB SDHC card.


Thanks for the great work.
