There's an oshkosh stub in 2.6 but for various reasons we cannot give
out the corresponding server. But we're working on an alternative
implementation which should be availabe in a not too distant future.
bmodfs is something different. bmodfs is an implementation of the file
provider API and is used by programs to get files. E.g. the loader uses
the fprov API to get the binaries it is supposed to start, or L4Linux
gets its RAMdisk this way. It's read-only. So L4Linux is just using it,
no driver (stub) involved.
We don't really have an IDE driver. Nevertheless there's a block stub in
2.6 which currently basically works only on UX as there's a block server
which goes down to the host FS for storage.
IMHO network support is far more important as one can do storage over
network but not vice versa. For the rest we'll see.
