For me it works read-write and out-of-the-box on a vanilla kernel.
(I added this stuff a few months ago. Found in 2.5 (which I use).
Am not quite sure about 2.4.)

2.5.32, 2.5.33 are fine here.]

Hmm.  So if I was to grab 2.5.${LATEST} and try porting the sddr09
driver back to 2.4.${CURRENT} ....

Thanks for the pointer.

Hmm. You do not confuse two situations, do you?
In the past few days I made two devices work.

One was a Feiya 5-in-1 CF / SM / SD card reader
(Vendor Id: 090c, Product Id: 1132, Revision 1.00).
It returned a capacity that is one too large, and becomes
very unhappy if one tries to read a sector past the end.
So, a flag was needed to tell that the result of READ CAPACITY
needs fixing.

The other was a Travelmate CF / SM / SD card reader
(Vendor Id: 3538, Product Id: 0001, Revision 2.05).
It became unhappy when MODE_SENSE asked for too much data.
A patch on sd.c solved this.

Seems reasonble, Matt, any objection?

Linus already added this patch to his tree :)

Nope, not confused.

I'm trying to find out why Windows doesn't choke on the strange
READ_CAPACITY value.  My guess is that there is code somewhere to
universally fixup READ_CAPACITY, and I'd like to know what the magic
formula is.

The MODE_SENSE bit is fine by me.  But it's a SCSI change, so I'm not the
person to ask.  The fix to sddr09.c for that seems reasonable, but you put
it all together and I haven't had time to split it up.  Of course, I fully
expect the changes to MODE_SENSE in the SCSI layer to break other USB
devices, but there is only one way to find out....

It's not that hard.  No matter what the problem is, tell the customer 
to reinstall Windows.

Speaking of sddr09 devices (of which I possess one), what's the current
state of support for the sddr09?  Last I knew, at the time when I finally
got mine working, the sddr09 was only supported read-only, since there
were not-fully-understood issues that resulted in filesystem corruption 
if you tried to write to it.  Currently, the driver will still allow me
to mount it only as a read-only filesystem.  Can write support for the
sddr09 be expected any time soon?

I'd like to hold off a few more days while I try to find out what the
'secret sauce' that the other OSes use for a device like this.

Oh, and I don't think the INQUIRY changes co-mingled in with the other
stuff is really any good.
