sdhci is working fine here on my Panasonic CF-R4. Read speeds seem to be about 
1.5MB/s with writes being a tad slower. This is on a 1GB Lexar SD card using 
FAT.  I have tested both 2.6.16-rc6-mm1 and a patched 2.6.15 without issues.

I can provide logs etc if required, but at present I am happily using the 
driver. I'm not subscribed so please cc me if required.

SDHCI seems to be working well on my Dell Inspiron 9300.

But I have concerns over maintenance of the code -- there does not
seem to be a functioning (for me) email address for a maintainer.

Cheers

You don't seem to have any problems reaching the mailing list hosted on
the same mail server as the address directly to me. :)

In looking at the patches in -mm, I see the following 5:
	secure-digital-host-controller-id-and-regs.patch
	secure-digital-host-controller-id-and-regs-fix.patch
	mmc-secure-digital-host-controller-interface-driver.patch
	mmc-secure-digital-host-controller-interface-driver-fix.patch
	mmc-sdhci-build-fix.patch

Is that all that is needed for this feature?

If so, I'll go try it out now...

thanks,

Tried it out and it works great (also see it's in 2.6.16-git9 now).  Hm,
my laptop's slot also supports xD cards, which your patch set does not
yet support, right?

thanks,

And will never do. Different hardware, interface and protocol.

Doh, you are right, sorry about that.  It's a totally different PCI
device, I should have looked before writing that.

Anyway, thanks again, this is working fine here.

Reverse engineering has been rather fun, so given access to some
hardware and enough time, I'll might just produce another driver or two. ;)

O2 Micro SD readers still don't work; I can't offer hardware very easily, but 
I'd be more than glad to provide a networked box with root access..

Thanks, but during the initial development it is more or less necessary
to have the hardware directly available.

Do you know if this hardware can be obtained in some other way than buying an 
entire laptop?

I've been looking high and low for any SD/MMC reader that can be used in
a standard PCI slot, but so far all I've found is a SDHCI-based
development board from Arasan. So it doesn't look like it. :-/

Ahh.. your email is different from the non-functioning email address
that you have on the patch itself (linked to from your web site):

     sdhci-devel@list.drzeus.cx

That one above didn't work for me, and until now I had assumed
it to be your preferred address (aka. /dev/null).

Cheers

Must have been something temporary because it evidently works just fine
for you right now. Also, the maintainer address listed in the patch is
drzeus-sdhci AT drzeus DOT cx, which Greg successfully mailed to earlier
today.

Did you try the one listed in the MAINTAINERS portion of the patch:

	+SECURE DIGITAL HOST CONTROLLER INTERFACE DRIVER
	+P:	Pierre Ossman
	+M:	drzeus-sdhci@drzeus.cx
	+L:	sdhci-devel@list.drzeus.cx
	+W:	http://mmc.drzeus.cx/wiki/Linux/Drivers/sdhci
	+S:	Maintained
