Well...  I just did a diff of the files I modified to get my 1Gig Microdrive
working and I notice some differences.

Here are the diffs from my working kernel and an rsync of Ben's tree I did on
Dec 1.

I see that idecs_register has been removed in favor of ide_register?

I don't know why this was done.  I don't have time to upgrade my kernel right
now but I will try later.  What I do know is the "ide_disable_irq_on_probe" was
required because the 1Gig does not work with the std disable of IRQ's.
However, I think the 340Meg did?

Sorry I could not be of more help.
