AUTOBOOT_DELAY is a different one, it waits for user interaction before
trying to start the kernel..

drive startup times could be an issue though

Could you try some things:

 * update to the latest svn revision (17 as I write this) and make sure
   you enabled the following option (which is new)

     # Add a short delay when polling status registers
     # (required on some broken SATA controllers)

 * if that doesnt help: try whether the disk is detected as hda instead
   of hde. This might happen with the current code.

 * enable the two options: DEBUG_PCI and DEBUG_IDE in the config file.
