I can confirm my c1000 has working SDIO which supports 4 bit mode and DMA/irqs
I have it working here (at work) with a WiFi card. Even a debug driver is achieving 4.5Mbps, and it should go faster than that.
Now the bad news:
I am not using Sharps sd module, but our own driver. SDIO drivers will not be open source - you have to pay royalties and licenses, and may not distribute the protocol.
So if some 3rd party (comercial) were to make Zaurus WiFi SDIO cards, and ship pre-build modules, this would be entirely possible, at least on a c1000.
Thanks,
Tim

I assume you are familiar with the C-Guys SD WiFi card discussed above in this thread? There has been progress adapting the C-Guys driver for that card at least to support memory cards above 1 GB recently, as explained in several threads.
Maslovsky, the man responsible for the Cacko improvements to the Sharp ROM, has my C-Guys card now. To the extent that there are software pieces missing between what C-Guys created and what you have, he might be in a good position to judge whether the gaps can be closed.
Anton, what do you think? tjchick, what specifically can you offer beyond what is available from C-Guys? Are there parts of your driver not within the SD license that could be released open source? Would that be useful absent the proprietary portions? Could parts of your work be adapted to the C-Guys driver, which is readily available?
