The only thing which matches the number of sectors is at word 100 which
is in reserved area. What's going on here?
Looks totally corrupt. Functioning ITE firmware RAID produces a fairly
poor response which is why we fix up the DMA flag but does report the
volume size correctly.
What firmware rev is this mess coming from ?
The firmware revision was 1.7.1.93
I have the capacity to boot with firmware version 1.41. I did this with
the 2.6.20 kernel and hdparm --Istdout /dev/hde produced this:

Interpreted by hdparm --Istdin, the meaning is the same.

On Wed, 9 Jan 2008, Tejun Heo wrote: hdparm -d1 isn't supported (yet). pata_it821x will configure DMA automatically. OK. So prior to rebooting 2.3.23.12 (boot log attached), I disabled hdparm for my hde raid array during the boot process. However, after booting, hdparm still shows that dma is not set on the array and the drive behaviour matches that. Can you post full boot log?
