[patch, 2.6, ppc] some modular framebuffer support

[Jens Schmalzing]

Hi,

the following patch allows some accelerated framebuffers (aty128fb,
atyfb, radeonfb, and rivafb) and framebuffer console support itself to
be built as modules on ppc.  Tested on a Powerbook Pismo, works very
well including XFree86 and DRI.

The first hunk suppresses a warning only, not sure about it.

Regards, Jens.
