[LinuxBIOS] [PATCH] Remove Bitworks IMS

[Corey Osgood]

Well, as there seems to be a lot of cleaning up going on lately, might
as well add this to the docket. The attached patch removes the Bitworks
IMS, as 1) there's no video support for it, 2) no one objected when this
was discussed previously, and 3) no one seems to have one, and they
aren't readily available. Any comments are welcome.
