2 part question:
a) will there ever be compatibility such that the SDHC cards can be used in a zaurus?
b)is it possible to use regular SD cards that have a capacity greater than 4 GB (when/if they come out)??
This has been mentioned a few times already in forums.
SDHC has a hardware and and software components to it.
The software component is done and is availalble for the latest 2.6 kernel. It will eventually filter down to the Z ROMs based on 2.6 if it hasn't already been done. However, even when it does, it won't be too useful to the Z because the Z does not have the necessary SDHC hardware.
As far as greater than 4GB non-SDHC cards. Well, anything is possible but, I highly doubt it since the manufacturers have to closely follow the SD stardards so they can continue to use the SD trademark. Most manufacturers wouldn't consider it worth the legal hassle to produce non-SDHC high capacity cards.
