Is there a way to issue the ATAPI 6 "SET MAX EXT" command using the HDIO_DRIVE_CMD ioctl?  As of 2.4.18 kernel, there doesn't seem to be a way to write the high order bytes to the IDE controller to implement the command for a 48bit LBA drive.  Would HDIO_DRIVE_TASKFILE work instead?

Take a look at code in drivers/ide/*.c related to CONFIG_IDEDISK_STROKE...
