AFAIK there is ext2fs code in blob, which can be used to
fetch files from a ext2 disk image.

The problem is that you need to be able to access your disk
somehow. There is low-level IDE and CF support in BLOB, but AFAIK
there is some glue code missing.

So: The bits are there, ist just a matter of putting them together.

There were discussions recently on blobs IRC channel on that subject
and it was agreed upon that IDE and CF code need proper massaging to put
it into shape, like the current ethernet and serial code. The filesystem
access code needs similar treatment.

Well, simply fetch blobs current CVS version, look how the ethernet
stuff is done (the low-level driver are nicely abstracted into a generic
driver struct).

The same is needed for the current IDE and CF code, and for the FS access stuff.
