althogh its off topic to the original post they do talk about SD cards and the guy writing the new SD card driver:
I got this message off the opentom mailing list from Thomas Kleffel:
ok, I think i need to clear up the SD-Card confusion a bit. There are currently 3 different SD card drivers there.
1) the early binary driver from TomTom (sd.o). Even if it is listed as GPL, it is not availabla as source. This is not TomTom's fault. TomTom signed a contract with the SD card driver association that forbids them to disclose their oh-so-secret intelectual property...
2) the early OpenTom driver. This is a hack I did about a year ago when driver #1 was only available for 2.4. I hacked SD-Card support into the MMC framework. This was only a quick hack, but however the 2.6.14-SD-Card support is somewhat based on it.
3) the new OpenTom/TomTom driver. I was paid by TomTom to develop a new open source SD card driver. It modifies the current MMC framework and is pretty stable and fast (6-8 MB/s). It is a clean implementation as I didn't sign anything with those SD-Card people. It is almost finished and will be available "really soon" ™.
So, what do those drivers do?
1) stable, a bit slow, closed source, no 2GB cards
2) stable, really slow, open source, no 2GB cards
3) stable, really fast, open source, 2GB cards - but not yet available wink.gif
I will talk to Christian about getting my hands on a Zaurus.
