Well you can download source of kernel from pogoplug and recompile it. If you have linux workstationyoucan recompile kernel or just modules. What modules are youlooking for ?
... I can't say how plausible. Then there comes the concern over possible kernel requirements for the drivers. I should be able to help out with drivers, ... on the type and status of the drivers, and if they come in a source tarball, etc.
The lower level processor information is under NDA. But, because Linux is under GPL....the source code for the kernel must be released. See ---> https://pogoplug.com/opensource
