Question to the site admins:
A few days ago, I uploaded a custom kernel for the 5500, compiled to allow async (faster) writes to SD & CF cards (see my thread on CONFIG_FS_SYNC). Since it still hasn't shown up available for download, I re-submitted it (upon user request, assuming there was a problem with the original upload), this time as a .zip file. Just wanted to point this out in case the original upload is still pending validation, you can disregard the other one.
