The sd8xxx driver is open source (although it requires proprietary firmware) and available under the GPL. But why is it not on palm's open source packages site? Where is the source? Didn't find it under http://opensource.palm.com/1.1.3/index.html

The original Marvell GPL sources are published in this download: http://www.marvell.com/drivers/driverDisplay.do?driverId=203 however the palm modifications to these sources do not appear to be published.
