I now have a u-boot.kwb that I've flashed into two of my Dockstars... they work perfectly (AFAICT), conform to the footprint that Jeff Doozan set down (in terms of environment and values).
I've tested serial, netconsole, flashing, tftpboot, loading u-boot into SDRAM, and even running both the CloudEngines PogoPlug software on them (again, following Jeff's setup) and Jeff's Rescue System. All seem to work just fine - I've been testing/checking for the last 3 days.
At it boots stock Debian 3.2 kernels (without the weird EMBEDDED config option ), since it has the DisableL2Cache patch applied to the source (2011.12 stable uboot).
If any ALARM folks (that already have JTAG experience, just in case) are interested in testing it, please ping me back.http://forum.doozan.com/read.php?3,6965,7081#msg-7081
