What is the state of FreeBSD on the SheevaPlug?

I've been developing and testing an application on the plug, both on Linux and FreeBSD. Linux is a PITA, but it does support the SD card. Running FreeBSD from an NFS mount gives me everything I want, quite stable, but no way to sell these devices in a standalone way as we can't store any data inbetween reboots (USB port is in use by a GSM device).
So getting the SD card working would be great. I've seen some commits lately in the gpio and mmc area but still no support for the Marvell SD. Tried even to compile your mv_sdio.c driver into the dev/mmc directory (adding appropriate changes to conf/files and mudules/mv_sdio), but I'm just not experienced enough for this kind of thing.

The code to me seems to be using a lot of "undeclared identifiers", for which I haven't found any #defines anywhere. Is there some header files that you haven't published or is this just too unfinished to test?

Anyway, as you might have noticed, I would really like to get SD support for the sheevaplug working on FreeBSD. If there's anything I can do to help here (including a little financial sponsorship), please let me know.

Kind regards,
Ruben
