What happened to /dev/hda3 and /dev/hda4? How can there be a /dev/hda5
without all the partitions in between?

Perhaps qtparted reads the partition table directly, rather than
relying on the kernel for this information.

This is pure guesswork, but maybe the kernel stopped when it couldn't
find /dev/hda3 and assumed that there was nothing beyond.
Maybe creating dummy partitions /dev/hda3 and /dev/hda4 would allow
the kernel to find /dev/hda5. It's worth a shot.
I'm not even addressing the issue of SCSI vs ATA. I'll leave that
to those who know more about it.
