No, there won't be any problems as long as you redistribute your modified
version under the same license as the original one.

I also recommend to rename the DLL and the driver files to avoid any
problems.

No, you can't insert your company's name in the copyright field of the
driver/DLL
property list. Simply because you are not the copyright holder of the software.

To solve this problem you could just replace the copyright string with a link
to a document (something like "see copying.txt") that explains the copyright
situation in more detail, contains the copyright holders (and links to your
company's website for support!).

Hope this helps,
Stephan
