I just found this announcement
Delkin Announces Secure Digital to CompactFlash Adapter
Now you can use your SD/SDHC cards in CF devices.
Software has long been cross-platform but now your SD and SDHC cards can be cross-platform as well, thanks to Delkin's new SD/SDHC to CF adapter. Just insert your SD or SDHC card into this small adapter and you can use SD/SDHC cards in any CF-compatible device including cameras and card readers.
This plug-'n-play adapter is also hot swappable and comes with a 2 year limited warranty. The device is shipping now at a price of $29.99.
