My 2G SD card did not work in any device I had,  I ended up buying the
only USB reader that claimed support of 2G SD in Yokohama Yodobashi Camera.

Which shop offered to let you try? The one I went to said they wouldn't.

I was hoping it was a driver problem.  SD is a proprietary protocol so
the drivers still have bugs.  I  have not had time to check but I
believe 7XX series use 255 series cpus which are limited to single
channel MMC/SD.  Our 2G SD card may not support this mode of operation. 
I did however read that these particular SD cards have upgradeable
firmware so it might be possible. I was also told by the shop I bought
the SD card from that the Zaurus would work with the 1G model of the
same card so it might just be a Linux driver bug.

If you format the sd card make sure you don't use fat16.  If you do it
will become a 1G card and you will have to use the tool on the following
page to restore it to a 2G card.
