Can I find information anywhere as to what this ranges command actually means?
I was assuming it has something to do with memory mappings, but I didn't find
any info as to what in particular the 0x2f _means_.

It does indeed work. I am a bit surprised that noone seems to be running
FreeBSD on a dockstar seriously enough to run into these problems.

Some ugly problem in connection with USB seems to rear it's head atm: if I
fsck a filesystem, it finds a lot of DUPs and starts deleting perfectly fine
files. I changed to using sync as well as disabling clustered reads and
writes. Maybe I'll find the time to investigate this issue as well.

I hacked a bit on the gpio/led driver to make the LED work with gpioled, I'll
post a patch to the mailing list when it's cleaned up if that's ok.
