HP Jornada 620LX hangs when trying to use root fs

Hello ppl

I'm trying to bring up NetBSD v3.1 on a HP Joranda 620LX with an installation
on a CF card, but the box hangs leaving the following information:

[snip]
...
boot device: wd0
root on wd0a dumps on wd0b
root file system type: msdos
[/snip]

Shouldn't the file system type be ffs?

I searched already the archives w/o finding any helpful hints.

I've already set up a NetBSD/hpcarm box (HP Jornada 720) in a quite similar
way. I followed the well-known onlamp-article, too.

I've tried both, the binary packages with the GENERIC kernel from NetBSD's
FTP server and a cross-compliled distribution + kernel based upon recent (as
of 2 days) sources of NetBSD v3.1_PATCH.

Any ideas what could be the problem?
