Put this together last night. It will log the entire SD card init process to a text file on a USB flash drive. To use it all you need to do is connect a FAT32 formatted flash drive and load the ELF with uLaunchELF. Once it's complete it will automatically exit and there should be a new file on the flash drive called "sdcard_log.txt".

I encourage anyone who's having compatibility issues to run this and submit the logs.
Below is the log for that 16GB Sony card that doesn't work.
