75000 tiles is not a lot:

Yes, thats over 2 million files :)
TangoGPS works fine ...
Not all SD cards are created equal - many (including mine) require a
reduced clock speed and then they are completely stable. I keep running
out of inodes - ext3 sucks, even when created using maximum inodes -
then fsck really takes forever! I believe reiserfs which is a far
better file system in my opinion is available in 2.6.29 SHR (I am stuck
on 2.6.28 as 2.6.29 gsm doesnt work for me.) - stabler and doesnt have
inode limits.
Try creating an init.d script to run at boot:
root at om-gta02 ~ $ cat /etc/init.d/sd_clk
#!/bin/sh
echo 10000000 > /sys/module/glamo_mci/parameters/sd_max_clk
root at om-gta02 ~ $
and make sure its mounted async
